Problems solved by technology

[0007] The insulating material of this formula adopts two-step cross-linking method, that is, first mix A material and B material in proportion and then extrude them together. After extrusion, heat in warm water at 90°C-95°C for 8-10 hours for cross-linking. , so that the performance of the cable material meets the specified requirements, that is, the thermal extension index requirements, which not only increases the production cycle, but also wastes energy

Abstract

The invention relates to a silane crosslinked polyethylene insulated cable material, which is formed by mixing 100 weight portions of materials A and 2 to 3 weight portions of materials B, wherein, the materials A are mixed by ethenyl trimethoxy silane, tetra (beta-(3, 5-di-tertiary butyl 4-hydroxy benzene)monoprop) pentaerythritol ester, diisopropylbenzene peroxide, low density polyethylene and polyethylene, and the materials B are mixed by low density polyethylene, dibutyl zinc laurate and tetra (beta-(3, 5-di-tertiary butyl 4-hydroxy benzene)monoprop) pentaerythritol ester. The cable material is crosslinked in the air to reach the stated service performance rather than immersed in mild water and crosslinked after the production is finished; and the production period is short and the energy consumption is low.
