High Voltage Joints and Terminations upto 72,5 kV–145 kV3M Cold Shrink Termination Kits QT-III and

Joint Kits are designed to provide high

reliability and save you time and money.

They install quickly and easily, helping to

reduce potential craft errors. They require

no special tools, adhesives, torches, or

other heat sources. Once installed, the cold

shrink accessory creates a dynamic,

compressive environmental seal and

electrical interface without sealants or

adhesives.

The QT-III terminations meet or exceed the requirements of IEEE 48, Class 1, 69 kV and IEC 60840 for

72,5 kV. The QS-III joints meet or exceed the requirements of IEEE 404, for 69 kV and IEC 60840 for 72,5

kV.

3M™ Cold Shrink QS-III Splice Kit 5488A Series for 69 kVThe 3M™ Cold Shrink QS-III Splice Kit 5488A is a 69 kV–class splice for joining jacketed concentric neutral (JCN), tape shield, longitudinally corrugated (LC)

shielded, tape-over-wire (TOW) or wire-over-tape (WOT) shielded power cables. It is a cold shrink design sized to fit Type MV–90 or type MV-105 cables with

copper or aluminum conductor sizes ranging from 250 kcmil–2000 kcmil (120–1000 mm²). The cold shrink splice body is a one–piece molded design made

of specially formulated silicone rubbers, while the cold shrink jacketing is made of EPDM rubber for physical protection. Each splice manufactured is factory

tested to provide reliability. The product numbers containing "XB" are for crossbond or shield break applications.
