Description

A New Type of 35kV Insulated Drain Wires That Are Easy to Operate

technical field

The utility model relates to the technical field of live work, in particular to a novel 35kV insulated drain wire which is easy to operate.

Background technique

In the 35kV overhead line to carry out the work of disconnecting the no-load lead wire with the insulated glove method, for the safety of the operation, the operator needs to wear a full set of heavy 35kV insulating protective equipment, and the thread buckle of the existing drain wire is thin and closely spaced. It is necessary to turn the ferrule multiple times when the personnel fasten and connect the wires, and the workload and work difficulty are relatively large, which brings great difficulties to the live operation, prolongs the working time, and reduces the work efficiency.

Contents of the invention

The purpose of the utility model is to provide a novel 35kV insulated drain wire which can improve work efficiency and is easy to operate.

The purpose of this utility model is achieved by the following technical means:

A new type of 35kV insulated drain wire that is easy to operate, including a cable and two connecting fixtures, one connecting fixture is connected to the left and right ends of the cable, the two connecting fixtures are composed of an outer sheath and a conductor, and the outer sheath is coaxially fitted On the outside of the conductor, one end of the conductor is made with a jaw, the other end is connected to the cable, and the middle part of the conductor is coaxially made with a threaded buckle, which is characterized in that: the width of each threaded buckle is 2mm, and two adjacent The distance between the threaded buttons is 2mm, and the outer sheath is a transparent outer sheath made of transparent plastic.

Moreover, the cable is made of copper strands with a diameter of 12 mm wrapped with an EPR low-temperature rubber composite material.

Moreover, the jaw part of the conductor is made of copper alloy with good electrical conductivity.

Advantage and positive effect of the present utility model are:

1. On the basis of the original 35kV insulated drain wire, this insulated drain wire has been improved on the tightening thread, not only thickening the thread, but also lengthening the interval of the thread, which can reduce the workload of the staff to turn the ferrule , to reduce the difficulty of the job.

2. The cable part of the insulated drain wire is made of copper stranded wire with a diameter of 12mm wrapped with an EPR low-temperature rubber composite material. This design not only ensures good flow capacity and insulation performance, but the insulation performance meets the requirements of 35kV live work, and It has passed the type test, is relatively light, and has excellent wear resistance.

3. The conductive part of the insulating drain wire fixture and the jaw part are made of copper alloy with good conductivity, and the outer sheath is made of transparent plastic, which can facilitate the inspection of the metal ferrule and cable in the handle.

4. The utility model is a new type of insulating tool that is easy to operate, safe and reliable, low in cost, economical and durable, and suitable for popularization and application. The maximum rated continuous current of the insulating drain wire is 400A, and the rated voltage is 35kV, which can be well applied In the 35kV overhead line, the insulating glove method is used to disconnect the no-load lead wire, and the increase of the thread spacing and thickness can effectively improve the work efficiency, reduce the work intensity and improve the safety of the work.

Detailed ways

The embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings; it should be noted that the present embodiments are descriptive, not restrictive, and cannot limit the protection scope of the present utility model with this.

A new type of 35kV insulated drain wire that is easy to operate, including a cable 3 and two connecting fixtures, the cable is made of a copper strand with a diameter of 12mm wrapped with an EPR low-temperature rubber composite material. The left and right ends of the cable are each connected to a connection clamp. The two connecting fixtures are both composed of an outer sheath 2 and a conductor 1, the outer sheath is coaxially sleeved on the outside of the conductor, and the outer sheath is a transparent outer sheath made of transparent plastic. One end of the conductor is formed with a jaw 4, and the jaw part is made of a copper alloy with good electrical conductivity. The other end of the conductor is connected to the cable. The middle part of the conductor is coaxially made with threaded buttons 5, the width of each threaded button is 2mm, and the distance between two adjacent threaded buttons is 2mm. The maximum rated continuous current of the insulated lead wire is 400A, and the rated voltage is 35kV, which can be well applied to the 35kV overhead line to carry out the work of disconnecting the no-load lead wire with the insulating glove method.

The using method of the utility model is:

First, through the transfer rope, the electrician on the ground transfers the utility model (the new 35kV insulated drain wire) to the electrician in the bucket, and the electrician in the bucket installs the two ends in turn at the place to be installed. During installation, the worker grasps the part of the outer sheath, snaps the wire into the jaw of the utility model, and rotates the outer sheath until the jaw clamps the wire.
