Efficiency improvement in the production process and enhancement of the working environment! Introducing the manufacturing method for insulation materials for high-voltage power transmission cables.
Typically, power transmission cables are insulated with super clean cross-linked polyethylene around the conductor, but in ultra-high voltage transmission (approximately 500,000 volts), charge concentration occurs in the insulating part, leading to the problem of cable failure during transmission. To prevent this, a semiconductive material that slightly discharges electricity inside and outside the insulator is used as a cushioning layer. This document introduces a technology for continuous mixing of the semiconductive layer using a biaxial kneading extruder.
