supplyCold shrink cable head indirect in cable terminal

The cold shrink cable terminal head is the use of elastomer materials (commonly used silicone rubber and ethylene propylene rubber) in the factory injection vulcanization molding, and then expanded, lined with plastic spiral supports to form various cable accessories parts. In field installation, these pre-expansion pieces are placed on the end or joint of the treated cable, and the plastic spiral strip (support) of the internal support is drawn out and pressed onto the cable insulation. Because it relies on elastic retraction force at room temperature, rather than fire heating contraction like heat shrinkable cable accessories, it is commonly known as cold shrinkable cable accessories. The early cold shrink cable end head only uses silicon rubber cold shrink parts for additional insulation, and the electric field treatment still uses stress cone type or stress tape wrapping type.
