OPGW (Optical Ground Wire):1. Type: OPGW 2. Structure: Stainless steel loose tube, ACS and outside AA can be stranded to form the single layer. It is coated with anti-corrosion jelly between the stranding layers
Characteristics:(1) Bio-function of ground wire and communication cable, avoid a huge expenditure to re-erect and re-maintain;(2) Erect on top of power overhead line pole, need not to consider its best hanging point, electro-corrosion, and others.(3) In the process of old line transformation, cable's outer diameter and tension may be matched better than another ground wire;(4) Big transmission capacity, good and reliable communication; excellent mechanical and electrical property;Good security, long lifetime, and invulnerable to gun fire.

Application / Models
(1).OPGW cable is mainly used in 500KV, 220KV and 110KV lines, limited by power cut, security and other elements, mostly used in new lines. Its applications are: high voltage over 110kv, with a longer span (usually over 250M);(2).easy to maintain, easy for line span, its mechanical property can meet a big line span;(3).outer OPGW is metal armoring, with no influence for high pressure electro-corrosion and degradation;(4).to construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing high voltage line over 110kv;(5).For OPGW performance index, the more short circuit current, the more need a good conductor to be metal armor, and reduce tension strength, while, if the tension strength is certain, to increase short circuit current capacity, the only way is to enlarge metal section area, resulting in an increased cable Dia and weight, so that security is a question for line pole strength.

Founded in 1994, POWTECH invested by TAIWAN, is an independently owned international corporation, offers an established and effective range of power supply products and sells to a very broad spectrum of telecoms and industries.
The development restructure of the POWTECH Group allows POWTECH to take a more active role in its fast expanding international business. Now, POWTECH have founded 3 factories locate at North China and Mid China, with more than 600 staffs. Also Powtech have expand its business to fiber optical cable and metal accessories. Besides, Powtech has set up two brands: JETPOWER and OPTELEC. JETPOWER runs business of power supply products and OPTELEC runs business of fiber optical cable and metal accessories.
Under OPTELEC brand, we manufacture and distribute ADSS optical cable, OPGW optical cable, non-metal optical cable, Fusion Splicer, OTDR, Terminal tool kit, ADSS fittings, OPGW fittings, transmission line fittings, wire mesh cable tray, preformed cable tray, cable trunking, cable ladders, STG modules, STG magazines and frame, aimed at:
Power Transmission line
Data centers and facilities
Industry and workshop
And so on…
POWTECH is at the forefront of optical transmission, iron casting and digital control lathe processing technology enabling us to meet the diverse needs of the markets. POWTECH’s products have been approved by KEMA, SGS and CE 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.
