The bers,250m,are positioned in a loose tube made of a high modulus plastic. The tubes are lied with a water-resistant Iling compound.The cable core is FRP or metallic strength member( some structures need add PE as bedding layer in the strength member).Electric wires and tubes (and Hers) are stranded around the strength member into a compact and circular cable core. The cable core is lied with the Iling compound to protect it from water ingress. After two sides PSP are longitudinally applied over the inner sheath， the cable is completed with PE or LSZH outer sheath.

Good mechanical and temperature performance

Opto and electricity integrated, fully save pipeline resources

Electric and optical cable maintain relatively independent structure,easy to import, export and link when installation

Electricity lines, telephone lines, television lines, network lines,monitor lines and data lines are multi-one network, saves costs

Cable diameter and bending radius are small, freely install in small space and compatible with optical signal and electric energy transmission

Larger operating temperature range and construction temperature range
