Product 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

Founded in 1994, POWTECH invested by Taiwan, is an independently owned international corporation dedicating to develop, produce & distribute JETPOWER brand power supplies and OPTELEC brand optical cables.
The first JETPOWER branded online high frequency UPS was developed in 1994. Driven by customer requirements, we have developed OFF LINE UPS, Line-interactive UPS, Industrial Online UPS, outdoor UPS, telecom inverter, power inverter and home inverter. Through a decade of great efforts, we have made our JETPOWER branded power supplies widely used in the fields of finance, telecom, electric power, petrochemistry, custom and military field etc, and have been honorably commented by clients. Besides, we also cooperate with many famous power supply companies by OED/ODM, and now our products have been sold worldwidely, including Europe, South America, Africa, Middle East, Asia ^.
While the fast development of power supply, we also expand our business to optical cable and accessories. In 2006, we have set up our own OPTELEC brand to develop, manufacture and distribute ADSS cable, OPGW cable, optical cable, Fusion Splicer, OTDR, Terminal tool kit, ADSS fittings, OPGW fittings, link fittings, wire mesh cable tray, preformed cable tray, cable trunking, cable ladders, STG modules, STG magazines and accessories. Till now, our OPTELEC brand optical cable and accessories have been used in more than 20 countries' telecom lines' construction and power transmission lines' construction.
Powtech has passed the ISO9001 international quality system certification and has established a complete quality system from material source, process, assembling to testing. All Powtech products have been approved by KEMA, SGS and CE (LVD/EMC) or by customer-appointed safety agencies.
Not only do we pride ourselves on competitive prices, super technology and quality products but also we have value-added technical support. We can dispatch our engineer to customer's site for site installation and training, or we can provide online service to solve any problem during installation & operation. With the belief that there is no customer too big or too small, every customer deserves better service. POWTECH people anticipate growing and prospering with you, embarking on a way of success.
