3M™ Cold Shrink QT III 7640 S, 7650 S & 7660 S Series Termination Kit includes a 1 piece, skirted termination. It ensures a pliable, tight seal for jacketed concentric neutral and concentric neutral power cables. The conjunction of high dielectric constant material and silicone rubber insulation allows the termination to withstand voltages of 5 to 35kV.
Each kit contains sufficient quantities of material to make a one-phase termination. The termination assemblies consist of a skirted insulator, high dielectric constant (Hi-K) stress control tube, conformable Hi-K stress controlling compound, and built-in environmental top seal. The insulator is made of a dark gray silicone rubber with advanced tracking resistant and hydrophobic properties. Note: Lugs need to be ordered separately.
