Double Layer Stranded Optic Fibra Opgw Cable
Product introduction
Stainless steel optical unit is in the inner position. Compared with the central stainless steel tube, larger cable diameter and larger capacity of the optical fiber.
It is applicable to new aerial power route to satisfy the needs for big conductors and high voltage transmission, and is used to conduct large fault short circuit current to provide anti lightning protection.
