3M™ Cold Shrink QT III 7640 S INV & 7650 S INV Series Inverted Termination Kit includes a single conductor, skirted termination for outdoor applications for polymeric insulated copper wire screened cables according to IEC 60502 between 3.3kV to 33kV.
Each kit contains sufficient quantities of material to make three single-phase terminations. The termination assemblies consist of a tubular 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. Exceptions: For T-150 Kits, 150 kV impulse level meets the impulse requirements for 35 kV class equipment where indoor terminations are used. 7620-T Kits are designed and assembled with stress controlling compound only.
