Product Description

OPGW Cable

Description:
OPGW cable is the short form of Optical Fiber Composite Overhead Ground Wire. OPGW cable is suitable for installation on new power lines with double function of ground wire and communication. Especially for installation on normal voltage and extra high voltage power lines. OPGW cable can replace conventional ground wire of old power line with increasing fiber communication function. OPGW cable conduct short circuit current and provide lightning resistance.

OPGW Cable Structure: Central sealed aluminum-covered stainless tube
-- The optical fibers loosely places in a hermetically sealed Aluminum-covered stainless tube unit
-- Single or multi layer ACS and AA wires are stranded together around the central aluminum-covered stainless tube

OPGW Cable Features:
(1) Extremely good corrosion resistance
(2) Improved lightning resistance and fault current
(3) Double tube design offers better resistance of the optical fiber from moisture and horizontal fluid penetration resistance
(4) Small diameter, light weight and compact design
(5) No anticorrosion grease, clean environment, longer life
