The product is available in single-core and three-core types. The insulation tube of the termination is generally 650mm in length, but it can be extended to 800mm, 1000mm, or 1201mm according to customer requirements. Cross-linked cable heat shrink terminations adopt a dual grounding process. That is, the steel armor grounding wire and the copper screen grounding wire are separated, making cable pre-testing more convenient and reasonable.
For indoor and outdoor terminations, and at intermediate branch points of oil-impregnated cables, oil-blocking finger sleeves are used to prevent oil leakage, and an insulating finger sleeve is applied externally, ensuring the product is safe and reliable.
