CHELCO SPECIFICATIONS FOR CONSTRUCTION
1. GENERAL
THESE SPECIFICATIONS PROVIDE FOR THE CONSTRUCTION OF UNDERGROUND DISTRIBUTION
POWER FACILITIES, AS SPECIFIED BY THE GOVERNMENT. ALL CONSTRUCTION WORK SHALL BE
DONE IN A THOROUGH AND WORKMANLIKE MANNER IN ACCORDANCE WITH THE STAKING
SHEETS, PLANS AND SPECIFICATIONS. IF CONSTRUCTION WORK IS PERFORMED BY THE
GOVERNMENT’S CREWS INSTEAD OF A CONTRACTOR, ANY REFERENCE TO “CONTRACTOR” IN
THE NARRATIVE PORTIONS OR DRAWINGS OF THIS BULLETIN SHALL APPLY TO THE
GOVERNMENT’S CREWS. THE EDITION OF THE NESC (ANSI C2) WHICH IS IN EFFECT IN
ACCORDANCE WITH THE “EFFECTIVE DATE” RULE OF ANSI C2 SHALL BE FOLLOWED, EXCEPT
WHERE LOCAL, STATE, FEDERAL, CHELCO OR OTHER REGULATIONS ARE MORE STRINGENT, IN
WHICH CASE THOSE REGULATIONS SHALL GOVERN.
2. STORAGE OF MATERIAL AND EQUIPMENT
ALL MATERIAL AND EQUIPMENT TO BE USED IN CONSTRUCTION SHALL BE STORED SO AS TO BE
PROTECTED FROM DETERIORATING EFFECTS OF THE ELEMENTS. IF OUTDOOR STORAGE
CANNOT BE AVOIDED, THE MATERIAL AND EQUIPMENT SHALL BE STACKED ON SUPPORTS WELL
ABOVE THE GROUND LINE AND PROTECTED FROM THE ELEMENTS AS APPROPRIATE, AND WITH
DUE REGARD TO PUBLIC SAFETY.
3. HANDLING OF CABLE
CABLE SHALL BE HANDLED CAREFULLY AT ALL TIMES TO AVOID DAMAGE, AND SHALL NOT BE
DRAGGED ACROSS THE GROUND, FENCES OR SHARP PROJECTIONS. CARE SHALL BE
EXERCISED TO AVOID EXCESSIVE BENDING OF THE CABLE. THE ENDS OF THE CABLE SHALL BE
SEALED WITH SUITABLE END CAPS AT ALL TIMES TO PREVENT THE INTRUSION OF MOISTURE.
WHERE IT IS NECESSARY TO CUT THE CABLE, THE ENDS SHALL BE TERMINATED OR SEALED
IMMEDIATELY AFTER THE CUTTING OPERATION.
4. TRENCHING
ALL TRENCHING DEPTHS SPECIFIED ARE MINIMUM AS MEASURED FROM THE FINAL GRADE TO
THE TOP SURFACE OF THE CABLE. THE ROUTING SHALL BE A SHOWN ON THE STAKING SHEETS
AND PLANS AND SPECIFICATIONS UNLESS CONDITIONS ENCOUNTERED ARE SUCH THAT
CHANGES ARE NECESSARY TO ACCOMPLISH THE WORK. IN SUCH EVENT, THE GOVERNMENT
SHALL BE NOTIFIED PROMPTLY. IF ROCK OR OTHER DIFFICULT DIGGING IS INVOLVED, THE
CONTRACTOR SHALL DETERMINE THE NATURE AND EXTENT OF THE DIFFICULTY, AND THE
GOVERNMENT WILL DETERMINE WHETHER REROUTING, ROCK TRENCHING, DIRECTIONAL
BORING OR OTHER CHANGES ARE NECESSARY. LOOSE SOIL OR CRUMBLY ROCK WILL NOT BE
CONSIDERED AS “DIFFICULT DIGGING.” THE TRENCH WIDTHS SPECIFIED ARE MINIMUM AND
SHOULD BE INCREASED AS NECESSARY TO OBTAIN THE REQUIRED DEPTHS IN LOOSE SOILS.
WHERE TRENCHES ARE INTENDED TO MORE THAN ONE CABLE, PARTICULAR CARE MUST BE
TAKEN TO PROVIDE FOR EXTRA DEPTH AND WIDTH TO ALLOW FOR SOIL FALLING INTO THE
TRENCH DURING THE LAYING OF THE FIRST CABLES. CARE SHALL BE EXERCISED TO MINIMIZE
THE LIKELIHOOD OF WATER-FLOW SINCE THIS MAY CAUSE TRENCH DAMAGE AND REDUCTION
IN TRENCH DEPTH. IF THIS OCCURS, THE TRENCH MUST BE CLEARED TO THE SPECIFIED DEPTH
BEFORE INSTALLING THE CABLE. ALL TRENCHES SHALL FOLLOW STRAIGHT LINES BETWEEN
STAKED POINTS TO THE EXTENT POSSIBLE. SECONDARY AND SERVICE TRENCHES SHALL
EXTEND IN A STRAIGHT LINE FROM TAKEOFF POINTS WHEREVER POSSIBLE. THE TRENCHES
SHALL BE DUG SO THAT THE BOTTOM HAS A SMOOTH GRADE, TO THE EXTENT POSSIBLE.
LARGE ROCKS, STONES AND GRAVEL IN EXCESS OF ONE (1) INCH SHALL BE REMOVED FROM
THE BOTTOM OF THE TRENCH. WHERE THIS CANNOT BE DONE, A TWO (2) INCH BED OF SAND
OR CLEAN SOIL SHALL BE PLACED IN THE BOTTOM OF THE TRENCH. CONSTRUCTION SHALL BE
ARRANGED SO THAT TRENCHES WILL BE LEFT OPEN FOR THE SHORTEST PRACTICAL TIME TO
AVOID CREATING A HAZARD TO THE PUBLIC AND TO MINIMIZE THE LIKELIHOOD OF COLLAPSE
OF THE TRENCH DUE TO OTHER CONSTRUCTION ACTIVITY, RAIN, ACCUMULATION OF WATER IN
THE TRENCH, ETC.
5. MINIMUM BENDING RADIUS OF CABLE
THE MINIMUM BENDING RADIUS OF PRIMARY CABLE IS TWELVE (12) TIMES THE OVERALL
DIAMETER OF THE CABLE. THE MINIMUM BENDING RADIUS OF SECONDARY AND SERVICE CABLE
IS SIX TIMES THE OVERALL DIAMETER OF THE CABLE. IN ALL CASES THE MINIMUM RADIUS
SPECIFIED IS MEASURED TO THE SURFACE OF THE CABLE ON THE INSIDE OF THE BEND. NO
CABLE BENDS SHALL BE MADE WITHIN SIX (6) INCHES OF A CABLE TERMINAL BASE.
6. CONDUIT
ALL EXPOSED ENDS OF CONDUIT SHALL BE PLUGGED DURING CONSTRUCTION TO PREVENT
THE INTRUSION OF FOREIGN MATTER AND MOISTURE. BURRS OR SHARP PROJECTIONS SHALL
BE REMOVED TO PREVENT DAMAGE TO THE CABLE. RISER SHIELD OR CONDUIT SHALL EXTEND
A MINIMUM OF EIGHTEEN (18) INCHES BELOW GRADE AT ALL RISER POLES. IF FULL ROUND
CONDUIT IS USED AS A RISER SHIELD, AN END BELL SHALL BE INSTALLED ON THE LOWER END
TO PREVENT DAMAGE TO THE CABLE.
7. CABLE INSTALLATION IN CONDUIT OR DUCT
WHERE CABLE MUST BE PULLED THROUGH CONDUIT OR DUCT, THE OPERATION SHALL BE
PERFORMED IN SUCH A WAY THAT THE CABLE WILL NOT BE DAMAGED FROM STRAIN OR
DRAGGING. IF REQUIRED, THE CABLE SHALL BE LUBRICATED WITH A SUITABLE CABLE
LUBRICANT PRIOR TO PULLING CABLE INTO CONDUIT OR DUCT. IN PLACING PRIMARY CABLES,
THE STRESS APPLIED WHILE PULLING INTO DUCTS OR DURING OTHER PULLING OPERATIONS
SHALL NOT EXCEED THE LEAST OF THE FOLLOWING:
a. WHERE PULLING EYE IS ATTACHED TO THE CONDUCTOR, THE MAXIMUM PULLING STRAIN
IN POUNDS SHALL NOT EXCEED 0.006 TIMES THE CIRCULAR MIL AREA FOR ALUMINUM OR 0.008
TIMES THE CIRCULAR MIL AREA FOR COPPER.
b. WHERE A BASKET GRIP IS PLACED OVER THE CABLE, THE PULLING STRAIN SHALL NOT
EXCEED THE LESSER OF (1) THAT CALCULATED IN ABOVE OR (2) ONE THOUSAND (1000) THE
CABLE UNDER THE CABLE GRIP AND 1 FOOT FOLLOWING IT SHALL BE SEVERED AND
DISCARDED AFTER THE PULLING OPERATION.
c. IN NO CASE SHALL THE MAXIMUM PULLING TENSION EXCEED THAT RECOMMENDED BY
THE SPECIFIC CABLE MANUFACTURER.
d. AT BENDS, THE MAXIMUM SIDEWALL PRESSURE RECOMMENDED BY THE CABLE
MANUFACTURER SHALL NOT BE EXCEEDED.
8. TAGGING OF CABLES AT TERMINATION POINTS
AS THE CABLES ARE LAID, THEY SHALL BE IDENTIFIED AND TAGGED. THE IDENTIFICATION
SHALL BE OF A PERMANENT TYPE, SUCH AS THAT DONE ON PLASTIC OR CORROSION
RESISTANT METAL THE TAG SHALL BE SECURELY ATTACHED TO THE CABLE. PAPER OR CLOTH
TAGS ARE NOT ACCEPTABLE.
9. SPLICES
CABLE SPLICES SHALL BE OF THE PRE-MOLDED RUBBER, HEAT-SHRINK, OR COLD-SHRINK
TYPE, OF THE CORRECT VOLTAGE RATING AND SHALL BE INSTALLED IN ACCORDANCE WITH
THE SPLICE MANUFACTURER’S INSTRUCTIONS. SPLICES THAT DEPEND SOLELY ON TAPE FOR A
MOISTURE BARRIER SHALL NOT BE USED. NOT MORE THAN ONE SPLICE SHALL BE PERMITTED
FOR EACH TWO THOUSAND (2000) FEET OF CABLE INSTALLED UNLESS AUTHORIZED BY THE
GOVERNMENT. NO BENDS SHALL BE PERMITTED WITHIN TWELVE (12) INCHES OF THE ENDS OF
A SPLICE. THE CABLE OR CIRCUIT NUMBERS AND THE EXACT LOCATION OF ALL SPLICES SHALL
BE NOTED ON THE STAKING SHEETS (AS BUILT).
10. PRIMARY CABLE TERMINATION AND STRESS CONES
PREFABRICATED STRESS CONES OR TERMINATIONS SHALL BE INSTALLED IN ACCORDANCE
WITH THE MANUFACTURER’S INSTRUCTIONS AT ALL PRIMARY CABLE TERMINALS. THEY SHALL
BE SUITABLE FOR THE SIZE AND TYPE OF CABLE THAT THEY ARE USED WITH AND FOR THE
ENVIRONMENT IN WHICH THEY WILL OPERATE. ANY INDICATION OF MISFIT, SUCH AS A LOOSE
OR EXCEPTIONALLY TIGHT FIT, SHALL BE CALLED TO THE GOVERNMENT’S ATTENTION. THE
OUTER CONDUCTIVE SURFACE OF
THE TERMINATION SHALL BE BONDED TO THE SYSTEM NEUTRAL. A HEAT-SHRINK OR
COLDSHRINK SLEEVE SHALL BE INSTALLED TO SEAL BETWEEN THE BODY OF THE TERMINATION
AND THE CABLE JACKET.
11. SPECIAL PRECAUTIONS FOR CABLE SPLICES AND TERMINATIONS
A PORTABLE COVERING OR SHELTER SHALL BE AVAILABLE FOR USE WHEN SPLICES OR
TERMINATIONS ARE BEING PREPARED AND WHEN PREFABRICATED TERMINATIONS ARE BEING
SWITCHED. THE SHELTER SHALL BE USED AS NECESSARY TO KEEP RAIN, SNOW AND
WINDBLOWN DUST OFF THE INSULATING SURFACES OF THESE DEVICES. SINCE CLEANLINESS IS
ESSENTIAL IN THE PREPARATION AND INSTALLATION OF PRIMARY CABLE FITTINGS, CARE
SHALL BE
EXERCISED TO PREVENT THE TRANSFER OF CONDUCTING PARTICLES FROM THE HANDS TO
INSULATING SURFACES. MATING SURFACES SHALL BE WIPED WITH A SOLVENT SUCH AS
DENATURED ALCOHOL TO REMOVE ANY POSSIBLE ACCUMULATION OF DIRT, MOISTURE OR
OTHER CONDUCTING MATERIALS. A SILICONE GREASE OR SIMILAR LUBRICANT SHALL BE
APPLIED AFTERWARDS IN ACCORDANCE WITH THE MANUFACTURER’S RECOMMENDATIONS.
WHENEVER
PREFABRICATED CABLE DEVICES ARE OPENED, THE UN-ENERGIZED MATING SURFACES SHALL
BE LUBRICATED WITH SILICONE GREASE BEFORE THE FITTINGS ARE RECONNECTED.
12. SECONDARY AND SERVICE CONNECTIONS
A SUITABLE INHIBITING COMPOUND SHALL BE USED WITH ALL SECONDARY AND SERVICE
CONNECTIONS. ALL SECONDARY CABLE CONNECTIONS IN SECONDARY PEDESTALS SHALL BE
MADE WITH PREINSULATED SECONDARY CONNECTOR BLOCKS. DIVING BELLS WITH OPEN
TERMINALS INSULATING BOOTS OR MOISTURE BARRIERS THAT DEPEND SOLELY ON TAPE ARE
NOT ACCEPTABLE. ALL SECONDARY CABLE SPLICES LOCATED BELOW GROUND SHALL BE
PERFORMED WITH PREINSULATED
SPLICE KITS. DIVING BELLS WITH OPEN TERMINAL INSULATING BOOTS OR MOISTURE
BARRIERS THAT DEPEND SOLELY ON TAPE ARE NOT ACCEPTABLE. ALL TRANSFORMER
SECONDARY PHASE TERMINAL CONNECTIONS SHALL BE COMPLETELY INSULATED. IF THE
SECONDARY PHASE TERMINALS ARE THREADED STUDS, THE CONNECTION SHALL BE MADE
WITH A PRE-INSULATED SECONDARY TRANSFORMER CONNECTION BLOCK. IF THE
TRANSFORMER SECONDARY PHASE TERMINALS ARE INSULATED CABLE LEADS, CONNECTION
SHALL BE MADE WITH A PRE-INSULATED SECONDARY CONNECTOR BLOCK OR WITH A
SECONDARY PREFABRICATED SPLICE WHEN THE TRANSFORMER LEADS CONTINUE DIRECTLY
TO THE SERVICE. IF A TRANSFORMER IS SO LARGE THAT IT MUST HAVE SECONDARY SPADES,
THE SPADES SHALL BE INSULATED. BOOTS USED FOR INSULATION SHALL BE TAPED SO THAT
THEY CANNOT BE READILY SLIPPED OFF.
SECONDARY CONNECTIONS TO TERMINALS OF POLE-MOUNTED TRANSFORMERS SHALL BE
MADE SO THAT MOISTURE CANNOT GET INSIDE THE CABLE INSULATION. THIS MAY BE
ACCOMPLISHED BY COVERING THE TERMINALS AND BARE CONDUCTOR ENDS WITH AN
APPROPRIATE MOISTURE SEALANT. THE SECONDARY CONNECTIONS AND INSULATION SHALL
HAVE ACCOMMODATIONS FOR ALL FUTURE AND EXISTING SERVICES AS SHOWN ON THE PLANS
AND SPECIFICATIONS.
13. INSPECTION AND INVENTORY OF BURIED UNITS
BEFORE ANY BACKFILLING OPERATIONS ARE BEGUN, THE CONTRACTOR AND GOVERNMENT
SHALL JOINTLY INSPECT ALL TRENCHES, CABLE PLACEMENT, RISERS, PEDESTAL STAKES, AND
OTHER CONSTRUCTION THAT WILL NOT BE ACCESSIBLE AFTER BACKFILLING, AND AN
INVENTORY OF UNITS SHALL BE TAKEN. IF CORRECTIONS ARE REQUIRED, A SECOND
INSPECTION SHALL BE MADE AFTER COMPLETION OF THE CHANGES.
14. BACKFILLING
THE FIRST SIX (6) INCHES OF TRENCH BACKFILL SHALL BE FREE FROM ROCK, GRAVEL OR
OTHER MATERIAL WHICH MIGHT DAMAGE THE CABLE JACKET. IN LIEU OF CLEANING THE
TRENCH, THE CONTRACTOR MAY, AT THE CONTRACTOR’S OPTION, PLACE A TWO (2) INCH BED
OF CLEAN SAND OR SOIL UNDER THE CABLE AND FOUR (4) INCHES OF CLEAN SOIL ABOVE THE
CABLE. CLEANED SOIL BACKFILL WHEN USED SHALL CONTAIN NO SOLID MATERIAL LARGER
THAN ONE (1) INCH. THIS SOIL LAYER SHALL BE CAREFULLY COMPACTED SO THAT THE CABLE
WILL NOT BE DAMAGED. BACKFILLING SHALL BE COMPLETED IN SUCH A MANNER THAT VOIDS
WILL BE MINIMIZED. EXCESS SOIL SHALL BE PILED ON TOP AND SHALL BE WELL TAMPED. ALL
ROCK AND DEBRIS SHALL BE REMOVED FROM THE SITE, AND ANY DAMAGE TO THE PREMISES
REPAIRED IMMEDIATELY. PIECES OF SCRAP CABLE OR OTHER MATERIAL REMAINING AFTER
INSTALLATION SHALL NOT BE BURIED IN THE TRENCH AS A MEANS OF DISPOSAL. ALL SUCH
MATERIAL SHALL BE DISPOSED OF PROPERLY.
15. EQUIPMENT PADS (GROUND SLEEVES)
THE SITE FOR THE PAD SHOULD BE ADJACENT TO THE TRENCH AND NOT OVER THE TRENCH IF
AT ALL POSSIBLE. THE SITE SHALL BE CLEARED OF ALL DEBRIS AND EXCAVATED TO THE
SPECIFIED THE PAD SHALL BE INSTALLED LEVEL AT THE SPECIFIED ELEVATION.
16. TRANSFORMERS
TRANSFORMERS SHALL BE HANDLED CAREFULLY TO AVOID DAMAGE TO THE FINISH AND SHALL
BE POSITIONED IN ACCORDANCE WITH THE STAKING SHEETS AND THE PLANS AND
SPECIFICATIONS. ONLY QUALIFIED AND EXPERIENCED PERSONNEL SHALL BE ALLOWED TO
MAKE CONNECTIONS AND CABLE TERMINATIONS. FOR SINGLE PHASE TRANSFORMERS, THE
MAXIMUM NUMBER OF CABLES PULLED INTO THE TRANSFORMER SHALL BE SIX (6) RUNS (18
CABLES) OF 500 MCM. FOR THREE PHASE TRANSFORMERS, THE MAXIMUM NUMBER OF CABLES
PULLED INTO THE TRANSFORMER SHALL BE TWELVE (12) RUNS (48 CABLES) OF 750 MCM.
17. EQUIPMENT ENCLOSURES
EXCAVATIONS FOR SLEEVE-TYPE TRANSFORMER PADS AND OTHER BELOW-GRADE
ENCLOSURES SHALL BE MADE SO AS TO DISTURB THE SURROUNDING EARTH AS LITTLE AS
POSSIBLE. ENCLOSURES SHALL BE INSTALLED WITH SIDE WALLS PLUMB. WHEN ENCLOSURES
ARE OF FIBER, PLASTIC, OR OTHER SEMI-FLEXIBLE MATERIAL, BACKFILLING SHOULD BE DONE
WITH COVERS IN PLACE AND WITH CAREFUL TAMPING SO AS TO AVOID DISTORTION OF THE
ENCLOSURE. WHEN INSTALLATIONS ARE COMPLETE, THE COVER OF THE ENCLOSURE SHALL
NOT BE LOWER THAN AND NOT MORE THAN TWO (2) INCHES HIGHER THAN THE GRADE
SPECIFIED BY THE GOVERNMENT. SOIL IN THE IMMEDIATE VICINITY SHALL BE TAMPED AND
SLOPED AWAY FROM THE ENCLOSURE. AT THE GOVERNMENT’S OPTION, THE EXCESS SOIL
SHALL BE REMOVED FROM THE SITE OR SPREAD EVENLY OVER THE SURFACE OF THE GROUND
TO THE SATISFACTION OF THE GOVERNMENT.
18. WARNING SIGNS
EACH EQUIPMENT ENCLOSURE SHALL DISPLAY A “CAUTION” SIGN PLACED SO THAT IT IS
VISIBLE TO ANYONE ATTEMPTING ENTRY TO THE ENCLOSURE. ALSO, THE EQUIPMENT INSIDE
THE ENCLOSURE SHALL DISPLAY A “DANGER” SIGN SO THAT IT IS VISIBLE WHEN THE
ENCLOSURE IS OPEN.
19. GROUNDING
ALL NEUTRAL CONDUCTORS, GROUND ELECTRODES AND GROUNDABLE PARTS OF EQUIPMENT
SHALL BE INTERCONNECTED. ALL INTERCONNECTIONS SHALL BE MADE AS SHOWN ON THE
CONSTRUCTION DRAWINGS. A GALVANIZE GROUND ROD(S) WITH MINIMUM LENGTH OF EIGHT
FEET SHALL BE INSTALLED AT ALL EQUIPMENT LOCATIONS AS SHOWN IN THE CONSTRUCTION
DRAWINGS AND AT ALL CABLE SPLICES AND TAPS.
ALL PAD-MOUNTED EQUIPMENT ENCLOSURES, INCLUDING TRANSFORMERS, SHALL BE
GROUNDED IN SUCH A MANNER THAT TWO SEPARATE CONNECTIONS EXIST BETWEEN THE
ENCLOSURE AND THE GROUND ROD(S).
20. CABLE LOCATION MARKERS
LOCATION OF PERMANENT CABLE MARKERS SHALL BE AS SHOWN ON THE STAKING SHEETS.
