Silane‑Crosslinked PE Compound for ≤10kV Overhead Cables (YHS‑10G)

YHS‑10G

YHS‑10G is a silane‑crosslinked polyethylene insulation compound with 2.0 % carbon‑black content for overhead cables up to 10 kV, complying with JB/T10260‑2014. Supplied as a two‑component system of Material A and Material B, they must be thoroughly homogenized before extrusion. It features high tensile strength, excellent elongation, outstanding low‑temperature performance and superior dielectric property. Mixed A‑B material should be consumed within 8 hours without moisture contamination; cross‑linking can be completed by hot‑water bath or steam curing for overhead power cable manufacture.

Processing Guide

Recommended Processing Parameters

Processing Technics

This product consists of Material A and Material B. When in use, one package of Material A shall be paired with one package of Material B. The two materials must be mixed uniformly during application, and no moisture shall be introduced in the mixing process. Material A requires no drying. Damaged packages of raw materials are strictly prohibited from use, while flexible gas packages can be used after discharge verification. The mixed Material A and Material B shall be used up within 8 hours to avoid affecting the extrusion surface of cables.

Crosslinking Process:

Crosslinking is conducted via steam or water bath. Taking an insulation thickness of 1mm as a reference, the temperature is recommended to be controlled at 90℃, with crosslinking achievable in approximately 4 hours. For thicknesses exceeding 1mm, adjustments shall be made based on the actual thickness and required crosslinking degree to ensure the cable meets relevant performance standards.
