Main technical parameters: Fiber curvature radius ≥ 37. 01dB Applicable temperature range:-40~70 ℃ Tensile 6 strength ≥ 2000N Weight: ≤ 20kgOptical Phase Conductor (OPPC) Joint Boxes are designed to connect two OPPC fibre optic cables. These boxes must be installed without having contact to tower structure. It connects trunk cables like OPGW to patch panels in control rooms. It is erected as an ordinary phase line in the power transmission line, which can avoid fatal problems such as strand breakage and fiber breakage caused by OPGW being struck by. umber of over-head line applications for the transmission of information. We have been developing fittings for fib data transmission in such cables takes place via modulated. Splice boxes are required to be connected between the optical cables erected on the tower, and between the optical cables and the guide optical cables; usually the optical cables are not charged, so the design of the splice box does not require Consider this aspect, but in OPPC, since the current. The intermediate joint box can be divided into two types: pillar type and hanging type. Before installation and connection, select a suitable installation position, design a bench for installing the joint box, and fix the joint box on it to ensure the bending radius of OPPC and that OPPC is not.
