Method for Manufacturing Insulation Material for High Voltage Transmission Cables
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 (about 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.
