With the expansion of global’s power demand and the innovation of smart grid technology, its promote power optical cable market. Up to now, the ADSS (All-Dielectric Self-Supporting) cable and OPGW (Optical Ground Wire) cable is commonly used in the power system.
For the power system transmission, the customer will confused for choose the power optical cable.
As per our 16+ years experience on power system transmission, our professional team strongly recommend follow the one principle and five key factor confirm the OPGW cable type.
Five Key Factors:
1. The passing short circuit shall not affect the mechanical profermance of OPGW if any occurs happend;
2. The distance between OPGW and phase conductor shall meet the design requirements;
3. OPGW loading strenth shall meet the tower design requirements;
4. OPGW operation safety index shall greater than the phase conductor operating safety index;
5. OPGW core length is greater than OPGW own creep and temperature changes caused by the line length change rate.
