The intermediate joint box can be divided into two types: pillar type and overhang type. Before installing and connecting, choose a suitable installation position, design a stand for installing the joint box, and fix the joint box to ensure the bending radius of OPPC , And OPPC is not affected by wind and other pendulums.

 

The main technical parameters:

 

Optical fiber curvature radius

 

Applicable voltage level: 35KV

 

Fiber coil additional attenuation ≤0.01dB

 

Applicable temperature range: -40 ~ 70 ℃

 

Tensile strength ≥2000N

 

Weight: ≤20kg

 

Optical fiber composite overhead phase line (OPPC) is a new type of special optical cable developed in recent years.It is set up as a common phase line in power transmission and transformation lines. At the same time, it can avoid the electrochemical corrosion of the ADSS outer sheath. The junction box needs to be connected between the optical cables erected by the pole tower and between the optical cable and the guide optical cable; usually the optical cable is not charged, so the design of the junction box does not need Consider this problem, but in OPPC, because the current and communication signals are transmitted in a cable, the communication signals in the junction box are required to be connected to the equipotential level in order to safely and reliably isolate the high voltage and signals, and at the same time Because OPPC is powered on for a long time and there is a certain temperature, this puts higher requirements on OPPC installation hardware to ensure the safe operation of the line.

 

Features:

 

(1) Has the function of an ordinary joint box;

 

(2) The design of the OPPC connector box fully considers the actual situation of domestic circuits, and strives to achieve a simple and reasonable structure, safe and reliable operation and convenient construction.

 

(3) Because the optical fiber is placed in the phase line, there is no serious defect of broken strands and broken cores caused by dropping lightning on the OPGW ground wire; compared with ADSS, there is no serious damage to the optical cable due to the effect of strong magnetic fields or burned disconnection. Defects: The cable crossing height is obviously superior to ADSS optical cable. It is safe and reliable. Secondly, because the wires and the connector box have high voltage, they have the absolute anti-theft advantage.
