Title:
LOW-HALOGEN THIN WALL INSULATED ELECTRICAL CABLE FOR LOCOMOTIVE
Document Type and Number:
WIPO Patent Application WO/2022/037264
Kind Code:
A1
Abstract:
The present invention relates to the technical field of thin-walled electrical cables, and more particularly, relates to a low-halogen thin wall insulated electrical cable for a locomotive. The low-halogen thin wall insulated electrical cable comprises a conductor. The conductor is coated with a halogen-free flame retardant insulation layer, and an outer surface of the halogen-free flame retardant insulation layer is coated with a low-halogen flame retardant sheath layer. In the present low-halogen thin wall insulated electrical cable for a locomotive, a conductor is coated with a halogen-free flame retardant insulation layer and a low-halogen flame retardant sheath layer to form a thin-walled electrical cable, such that the flame retardant performance of the thin wall insulated electrical cable can be effectively improved. A high-temperature-resistant oil-resistant rubber is added to the halogen-free flame retardant insulation layer and the low-halogen flame retardant sheath layer, such that the electrical cable has improved oil resistance and flexibility and enhanced low-temperature resistance. Use of the low-halogen flame retardant sheath layer increases light transmittance of the thin-walled electrical cable, and ensures that the smoke density thereof is lower than 20%, thereby effectively improving performance of the electrical cable.
