10 kV Flame-retardant all-insulated multi-branch intermediate-break fiber splicing closure

Abstract

The invention discloses a 10 kV flame-retardant all-insulated multi-branch intermediate-break fiber splicing closure, comprising a flame-retardant insulated splicing closure body that is at least provided with a fiber composite elevated conductor main inlet and a fixture and is at least provided with a fiber composite elevated conductor main outlet and a fixture, as well as two fiber composite elevated conductor branch inlets and fixtures. Fiber portions of a fiber composite elevated conductor main incoming line, a fiber composite elevated conductor main outgoing line and fiber composite elevated conductor incoming branches are spliced in the flame-retardant insulated splicing closure body, a power carrier portion of each fiber composite elevated conductor branch and that of the fiber composite elevator conductor main outgoing line are connected or disconnected outside the flame-retardant insulated splicing closure body through an intelligent control switch. One-in and multiple-out offiber composite elevator conductors is achieved via the flame-retardant all-insulated splicing box, and construction of 10 kV voltage multi-branch line construction is advocated precedently.

Description

technical field [0001] The invention relates to the technical field of optical fiber composite overhead wires, in particular to a multi-branch intermediate open optical fiber connection for 10KV voltage. Background technique [0002] With the continuous advancement of reform and opening up, the quality of people's lives has been continuously improved, and more demands have emerged. For the construction of optical fiber composite overhead conductor lines with 10KV voltage transmission, there are many shortcomings, such as: the connection box of the line lacks a safe circuit breaker, the disconnection of the branch line cannot be controlled separately, the incoming / outgoing cable lacks a sealing structure, and the sealing effect of the joint box Poor, increasing the difficulty of winter construction, and large size, connection, construction, transportation are extremely inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invent...
