Application

This low-smoke zero-halogen (LSOH) flame-retardant control cable features fine bare copper conductors as its core and employs LSOH thermosetting EI5 insulating material. Manufactured in strict compliance with international standards such as BS 6360 and IEC 60228, it combines excellent electrical performance, safety and environmental protection attributes, and environmental adaptability. The product covers a range of cross-sectional area specifications from 0.5 to 1 mm², is rated for an operating voltage of 300/500V, and is widely applied in scenarios with high requirements for safety, temperature resistance, and insulation, including building electrical systems, industrial automation, rail transit, and new energy. It stands as an ideal choice for ensuring stable equipment operation and personnel safety.
