657TQ / BS6883

Our 657TQ, is designed to meet BS6883 standards for power and control systems in maritime environments. Featuring a LSZH sheath to minimize smoke and gas emissions during emergencies, our range includes the Type SW4 cable with Lloyd's Register approval for fixed wiring across ships and offshore platforms. Versatile for power, control, and lighting needs in all areas. Non-armoured for easy installation in accommodations and open decks, our cables offer durability and reliability.
