Cable Cores

TORAYCA™ carbon fiber is ideal for cable cores requiring high-capacity and high-efficiency at a cost-effective price.

Nowadays, power demand is increasing and high-voltage power grid systems need to be expanded, mainly in emerging countries. Cable cores traditionally use steel or aluminum, but for high-voltage power grid systems better transmission capacity and efficiency is needed.

Compared to conventional steel/aluminum cable core transmission, CFRP cable core transmission can provide several advantages.

Thanks to a 30% reduction in weight compared to aluminum conventional cable core transmission and a small coefficient of thermal expansion, CFRP cable core transmission can reduce transmission loss and double power transmission.

In addition, CFRP cable core transmission prevents the sag caused by high temperatures on the surface of the cable. This reduces construction costs by cutting the number of towers required, tower construction cost and lead time.

Carbon fiber is also rustproof, increasing the material life.

Since CFRP cable core provides high performance while also reducing costs, the cable core business looks set to grow significantly as a key application field for carbon fiber.
