Wire tightener

Technical Field

The invention relates to the technical field of street code wire tightening, in particular to a wire tightener.

Background

In the electric power construction and operation, the low-voltage insulated wire is a transmission channel for connecting a transformer low-voltage side with a user, and the street code is an electric power fitting nailed on a wall and used for fixing the low-voltage insulated wire and forming an effective distance with the wall body to keep insulation and prevent the insulating skin of the low-voltage insulated wire from discharging to the wall body after being worn by external force. Faults occurring in the low-voltage insulated wire are frequent, for example, the insulation skin is damaged to cause discharge to a wall body, the faults of the low-voltage insulated wire cause great influence on normal operation of a power grid, and if social personnel touch a leakage area, electric shock risks exist, so that fixing and protection of contact positions of the conducting wire and a street code need to be strengthened.

Insulated wires and street codes are bound together by binding wires in the prior stage, single-stranded plastic copper wires are used for binding straight line positions which do not bear the tensile force of the line, and turns which bear the tensile force of the line and terminal positions are wound and protected by self-dissolving adhesive tapes after being bound by the single-stranded bare copper wires.

Binding has the following disadvantages: firstly, the construction efficiency is low; secondly, the wire is used in a large amount, and each street code needs to be provided with 1 meter of binding wire; thirdly, the binding effect is determined by the construction level of constructors, if the binding is not tight, the low-voltage line is easy to be separated from the street code and directly touches the supporting iron piece, and the great electric leakage risk exists; if the binding is too tight, the insulation sheath of the low-voltage wire is damaged, and the possibility of electric leakage also exists.
