Abstract

The invention discloses an optical unit direct leading-down structure of an OPPC (Optical Phase Conductor) and a construction method of the optical unit direct leading-down structure. The optical unit direct leading-down structure is provided with an OPPC optical cable (1), a pre-twisted wire assembly (3), a first connection fitting (4), a second connection fitting (6), an insulator string (7) and an optical connection jumper (8) and is also provided with an optical unit leading-out connector (2). By the structure, a plastic pipe optical unit of the OPPC optical cable hung at a high altitude can be separated and directly lead down, and moreover, the structure is suitably used for the OPPC optical cable of which the plastic pipe optical unit is arranged at an arbitrary position in the OPPC optical cable. By the construction method, connection between the OPPC optical cable and the optical unit leading-out connector and connection and installation of the pre-twisted wire assembly, the first connection fitting, a remaining cable rack, the second connection fitting and the insulator string can be completed on the ground, the OPPC optical cable is pulled to a high altitude and then is connected to a cross arm of an iron tower or a telegraph pole after winding of a remaining cable segment, and finally, the plastic pipe optical unit is directly lead down. The construction method has the advantages of simplicity and convenience in construction.

Description

technical field [0001] The invention relates to an optical unit direct-lead structure of an OPPC optical cable and a construction method thereof. Background technique [0002] Optical Phase Conductor (hereinafter referred to as OPPC) combines optical units in the phase line, which can transmit optical signals while transmitting electric energy. While erecting power transmission lines, optical signal transmission links are built along the lines. One thing with two uses saves both material and labor. [0003] Since 2009, Guangdong Power Grid Corporation has developed a new type of OPPC optical unit separation and downlink technology. This new technology avoids two major problems in the original OPPC construction: one is to order in advance according to the distance between the interface position and the fixed-length distribution plate; the other is It is necessary to install a ground-to-ground high-voltage insulation wiring device on the tower, and connect the optical unit to...

AI Technical Summary

Problems solved by technology

[0007] However, the currently achieved OPPC optical unit separation technology still has certain limitations:

[0009] Second, when the composite optical cable has dual optical units, it is extremely difficult to separate and guide the two optical units.

[0010] Third, since the tension-resistant fittings are installed on the cable section after the optical unit is separated, it is not conducive to retaining the remaining cables for future maintenance.
