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.
