General Description: In order to prevent galvanic corrosion due to OPGW and different metal wires are in contact with each other to form galvanic effect,we designed and developed a OPGW cable model aluminium wrapping stainless steel pipe light unit,the cable without filling antiseptic ointment to fight the electric corrosion.

In order to avoid the stress of casing of fiber,fiber excess length must be greater than 0.4%,according to thetheoretical calculation and practical circuit operation general design in 0.40-0.70%.
