Product Description

Product Description

Optical Fiber Composite Overhead Phase Line (OPPC) is a new type of special optical cable developed in recent years. 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 lightning. , At the same time, it can avoid the electrochemical corrosion of the ADSS outer sheath. 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 and communication signals are transmitted in one cable, it is required that the communication signals be connected to the equipotential level in the junction box to reliably isolate high voltage and signals, and at the same time due to The OPPC is powered on for a long time and there is a certain temperature, which puts forward higher requirements for the OPPC installation hardware to ensure the operation of the line.
The OPPC splice box uses a “silicone rubber composite insulator” with the same voltage level as the line. According to different usage methods, it can be divided into intermediate type and terminal type. Generally, the intermediate junction box adopts a “conductive non-insulated junction box”, which is welded and connected at the upper junction box once; while the terminal junction box adopts a “high-voltage isolated insulating junction box”, which is welded and connected twice at the upper and lower junction boxes.
The intermediate joint box can be divided into two types: pillar type and hanging type. Before installation and connection, first select a suitable installation position, design a stand for installing the joint box, and fix the joint box on it to ensure the bending radius of OPPC , and OPPC is not affected by wind swings, etc.

Technical parameters

Product structure characteristics and working principle

Product features:
(1) It has the function of ordinary splice box;
(2) The design of OPPC splice box fully considers the actual situation of the line, and strives to achieve 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 the OPGW ground wire being struck by lightning; compared with ADSS, there is no serious defect of optical cable corrosion or burning and disconnection caused by the action of a strong magnetic field Disadvantages: The crossing height of the line is obviously superior to that of the ADSS optical cable, which is safe and reliable; secondly, because there are high voltages on the wire and the splice box, it has an absolute anti-theft advantage.
Basic structure:
The device is divided into upper and lower boxes, supported by insulators in the middle, pre-embedded optical fibers in the center of the insulators, and the upper and lower boxes are respectively equipped with fusion splicing and splicing structures, fiber storage trays, and residual fiber racks.
Working principle:
OPPC splice box adopts “high voltage isolation and insulation” technology to ensure safe, reliable and effective operation of OPPC line insulation. The specific structural design adopts the same voltage level “silicone rubber composite insulator.
