1U Threading blind plate

The threading blind is a commonly used power piping accessories, widely used in power line construction and equipment maintenance and other fields. There are two types of feedthrough blinds: box-type and non-box-type. Boxed blinds are used for connecting and branching cables, control cables, etc., while non-boxed blinds are often used to provide temporary protection or spanning after line cutting.

The working principle of feeder blinds is mainly to protect both sides of the line from damage by installing blinds at the intersection of power lines. During maintenance of electrical equipment such as insulators and switches, feedthrough blinds provide temporary circuit bridging for line cutting and repair. The use of feedthrough blinds can effectively avoid safety hazards such as short circuits and arcing caused by line cutting.

When selecting and using a feedthrough blind, you need to choose according to the line specifications and voltage level of the construction site. According to the provisions of the industry standard ‘pipeline instrumentation flow chart piping and fittings graphic symbols’, the threading blind needs to be set before or after the cut-off valve, and should be made in the flange at the back of the valve where there is a source of material, and there are gaskets on both sides of the blind. In addition, the feedthrough blind is shaped like a figure 8, made of sheet steel, and can be rotated to the open or closed position.

When using the threading blind, the following points need to be noted:

1. The specification and model of the feedthrough blind should match the line specification and voltage level.

2. the installation position of the feedthrough blind should be chosen at the line crossing and ensure that the blind is in close contact with the line.

3. Before installing the feed-through blind, the lines should be insulated to avoid short-circuiting and arcing and other safety hazards.

4. After the use of threading blind, it should be removed in time and stored properly for the next use.

In short, the threading blind is a commonly used electrical piping accessories, with the protection of the line, to provide temporary electrical bridging and other functions. In the selection and use of threading blind, need to choose and install according to the actual situation of the construction site, and pay attention to the safe operation, in order to ensure the safe operation of power lines.
