The Single and Multicore
cables complement each other.

While single core cables are widely used for domestic purposes, multicore cables are used in areas where space might be a constraint (medical equipment, aircraft) or in entertainment venues, theaters, heavy industries, etc. The single as well as multi core cables from Goldmedal are durable and heat resistant. They do not melt or burn easily even in extreme conditions.

Features

Manufactured from bright annealed 99.97% pure bare copper conductors these cables offer low conductor resistance. These wires are insulated with in house manufactured specially formulated PVC compound. The tough robust outer PVC jacket protects it from oils, greases, various chemicals and abrasions giving the wire a long life and ensuring electrical safety.

Applications

Multicore Cables are very versatile and can be used in control panels for heavy industries, heavy machineries, air-condition, motors etc.
