Tyco Electronics Energy Divisioncovers a wide range of porcelain andpolymeric transmission surgearresters. The Bowthorpe EMP rangeof arresters has demonstratedreliable performance inenvironments all over the world forover 60 years.

Bowthorpe EMP, unlike othermanufacturers, recognise that somePower Utilities require the need tomaintain the conventional ZnOporcelain surge arrester.

A program of continuous designupdate and development on theporcelain arrester has provided arange of surge arresters to meet thedemands of most system voltages.

Design Evaluated and Type Tested atthe HV Laboratory in Brighton.

Bowthorpe EMP were the firstmanufacturer to develop thepolymeric housed arrester forcommercial operation (1983).

Range of HV surge arresters inservice under the severest climaticconditions up to 550kV system.

3P6SR252 - Statnet 300kV

The series parallel construction comprises individualsurge arrester modules rated between 30 and 45kVinterconnected by means of corona free aluminium alloycross arm.

Each surge arrester module is completely impervious tothe ingress of moisture and utilises the high mechanicalstrength properties of the ZnO varistors bonded bycured resin impregnated glass fibre.

The seismic performance of the 500kV arrester has beenproven in two leading test facilities. Bonneville PowerUSA performed at Portland State University and NELEast Kilbride UK.

• No air gap therefore no internal ionisation• Light weight compared to porcelain• Ease of installation• Non shattering housing• Vandal proof• Tolerance to seismic disturbances• Patented glass fibre core design gives high mechanical

strength and void free construction• Optimised voltage stress grading eliminates need to

oversize stress grading ring, therefore the compactseries parallel can be installed in tight spaces withoutinfringing electrical or surge safety clearances.

• The diameter of the series parallel design has beencalculated to reduce the radial field stress to a mini-mum, even under adverse environmental conditions.

Porcelain surge arresters are available for applicationsup to 400kV systems.

Porcelain housing designs have been used by us forover 55 years.

From 1945 we produced porcelain surge arresters to thegapped silicone carbide pattern and since 1980 we haveproduced arresters to the gapless ZnO design.

The design consists of porcelain housing whichconforms to IEC-815 with an Aero Dynamic shed profile.

The varistors, spacers and locating rings are assembledunder compression with pressure relief diaphragms ateither end. The air void is evacuated and replaced withdry air, then sealed.

Routine tests are carried out to show that themanufacturing conforms to the current Internationalstandard.

Suitable for use on circuits where standing/inducedvoltages do not exceed 110v RMS.

Fast operation – Typical 5 microseconds with 11kA faultcurrent.

Internal spark gap module unit easily replaced afterfault current operation.

Fail safe feature ensures safety to personnel andequipment.

Service proven performance.

High internal impedance with low capacitance – doesnot interfere with track signalling circuits.

Safety, Connectors and Earthing Equipment


Airfield Lighting Box Type 2DCAFL4

There are few places more exposed to direct lightningstrikes than an airfield. In such situations lightningstrikes within the vicinity of the airfield can result inpermanent damage to electrical equipment.

Airfield lighting circuits are particularly vulnerable asthe associated cable networks present an attractive lowimpedance path for lightning surge currents to earth.The result of a nearby lightning strike can bepermanent damage to the control circuits unless asuitable lightning arrester is fitted to the lightingcontrol equipment.

The Lightning Arrester Type 2DCAFL4 is designed toprotect airfield lighting control equipment from theeffects of direct or indirect lightning strikes.

The arrester is provided with two metal oxide activeelements which are connected in parallel with thesupply cables. Installation requires only the cutting ofthe supply cables at a convenient place close to thecontrol equipment and connection of the arrester to agood electrical earth.

Arrester 2DCAFL4 can be fitted to new equipment butis primarily designed to be quickly installed on existingcircuits.

Surge CountersType SC12 & SC13

The Bowthorpe EMP range of SurgeArrester monitoring instruments arefully tested for use with anymanufacturers surge arrester. TheSC12 is a Surge Counter only, whilstthe SC13 provides the additionalmeasurement of total leakagecurrent. The analogue instrumentprovides a means of monitoring thecurrent through the arrester and theleakage current over the surface ofthe arrester housing. Significantchanges after installation mayindicate a deterioration in thearrester or a build up of surfacecontamination.These instruments, which require noauxiliary supply, are designed forinstallation in the earth connectionsof a single surge arrester oralternatively the SC12 may be usedwith the common earth of a threephase set. Fully weatherproofed andsealed for life they are housed in aone piece gravity die cast aluminiumcase coated to enhance its alreadyhigh degree of resistance to surfacecorrosion. The glass viewing windowis sealed in place, using a siliconrubber adhesive, and a desiccator isenclosed to ensure any residualmoisture trapped during sealing isabsorbed for the service life of thecounter. Mounting is effected bymeans of an integrally cast lug at the

rear of the case providing a singleclearance hole for the galvanisedsteel M12 bolt supplied.

The SC12 and SC13 are serviceproven and require no specialmaintenance or servicing apart fromgeneral cleaning of the glassviewing window and the mouldedepoxy resin line terminal bushing.
