3M Cold Shrink technology has been used

by the power industry or nearly 40 years,

providing dependable, time-saving solutionsor low to medium voltage installations.

Now, this proven technology has been

adapted or use in 69kV (IEEE)/72.5kV (IEC)

undergroundcable installations.

3M Cold Shrink Termination Kits QT-III

and Joint Kits QS-III are designed to provide

high reliability and save you time and money.

They install quickly and easily, helping to reduce potential crat errors.

They require no tools, sealants, adhesives, torches or other heat sources.

Engineered for fast, economical installatio

3M Cold Shrink Termination Kits contain everything you need to

terminate 69kV (IEEE)/72.5kV (IEC) solid dielectric, tape, longitudinally

corrugated (LC/HSG) jacketed concentric neutral (JCN), tape-over-

wire (TOW) or wire-over-tape (WOT) cable. Conductor size range is

2502000 kcmil (1201000mm2).

Termination Kits

Once installed, the cold shrink tube creates a dynamic, compressive

environmental seal and electrical interace without sealants or

adhesives. It resists ultra-violet radiation, ozone and industry-approved

cable cleaners.

Were with you in the trenchesEven the most innovative technology will have little benet, unless it

is matched to the application and correctly applied. Thats why all 3M

cable accessories are backed by a global network o technical support,

sales and supply chain specialists. Their expertise is always available

to help suggest alternatives or you to evaluate and select a solution

optimized or your requirements with training, installation assistance,

custom congurations and more.

These 3M Cold Shrink Joint Kits QS-III

contain a 69kV (IEEE)/72.5kV (IEC) class

joint or connecting jacketed concentric

neutral (JCN), tape-shield, longitudinally-

corrugated (LC) shield, tape-over-wire

(TOW) or wire-over-tape (WOT) shielded

power cables. The cold shrink joint body

consists o a one-piece molded design

made o specially ormulated silicone

rubbers, while the cold shrink jacketing

is made o EPDM rubber or physical

protection. Kits are delivered with a range

taking shear bolt connector that ts both

aluminum and copper cable conductors.
