Description
● Central AL-covered Stainless Steel Tube OPGW Cable:
OPGW Mainly used for power communication with accessories, relay protection,automatic transmission,installation together with high-voltage lines. The central AL-covered steel tube is surrounded by single or double layers of aluminum clad steel wires (ACS) or mix ACS wires and aluminum alloy wires. AL-covered Stainless Steel Tube design increases the cross section of AL, to reach a better fault current and lightning resistance performance. Apply to the transmission line which requires small diameter and large fault current.
● Fiber Type:G652D; G655C; 657A1; 50/125; 62.5/125; OM3; OM4 As Options
● Features:
►High quality IEC607948 IEEE1138 standards for designing, testing and producing with grade A materials available to ensure long-term reliability;
►Engineering support supervising and providing its own line of accessories hardware;
►Seal stainless steel tube superior protection to the fiber optical to moisture and extreme environmental conditions such as lightening;
►To construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing high pressure line over 110kv;
►Apply to the transformation of old lines .
● Applications:
►Commonly used in newly built overhead power lines;
►Can meet the requirements of big number of fibers and ultra high voltage (UHV) transmission lines;
►Can provide protection against lightning by transmitting large fault short-circuit current.
