Necessity of busbar heat shrinkable sleeve in power distribution

The busbar refers to the copper bar/aluminum bar in the power distribution cabinet, as well as the conductor used for the connection between the power distribution cabinet and the transformer. It is the power busbar in the electrical cabinet and has a large current flow capacity. Each branch line (branch row) is led down from the top by the busbar. That is, in the power supply system, the connection between the general switch in the electrical cabinet and the switches in each branch circuit is the copper bar/aluminum bar. The busbar heat shrinkable tube mainly provides insulation protection for the busbar/copper bar in electrical cabinets, switch cabinets, substations and other places. In the past, the copper-aluminum busbars in many scenes were naturally exposed, and many safety and production accidents occurred. In addition, the insulation spacing of the exposed busbar is very large, which cannot meet the design requirements. The emergence of the busbar heat shrinkable tube effectively solves a series of problems when the busbar is exposed.

Features of busbar heat shrinkable sleeve:

     1. Soft, low smoke and high strength, because the busbar may need to be bent during use, in order to ensure that the heat shrinkable tube and the busbar are completely fitted, it must have the characteristics of softness and high strength.

     2. Anti-electrical carbon traces, in order to prevent the product surface creepage, leakage, short-circuit through the tube wall, fire and other dangers, it is necessary for insulating materials to have the ability to resist electric carbon traces.

     3. The wall thickness is uniform and does not deviate from the wall. All heat shrinkable tubes are made of new materials, and no return material is added. The advanced technology avoids the eccentric wall phenomenon and affects the performance of the product.

     4. The busbar heat-shrinkable sleeve is simple to operate and easy to install. It is almost suitable for the insulation protection of all live conductors, and the power failure time is short, the cost is low, and the performance is long-term reliable. In this sense, the use of high-voltage busbar heat shrink The insulation treatment of the busbar by the pipe adapts to the new trend of power supply developing in the direction of safety and high efficiency.

Generally speaking, we put the high-voltage busbar heat shrinkable tube into the busbar, which is mainly used to solve the following practical problems:

1. Eliminate short-circuit faults caused by small animals such as mice or conductive foreign objects;

2. Prevent acid, alkali, salt and other chemical substances from corroding the busbar;

3. Prevent the electrified bare busbar from causing accidental injury to maintenance personnel;

4. Effectively improve the anti-pollution flashover level of the busbar system;

5. Prevent discharge accidents caused by ice and snow sticking;

6. The heat shrinkable creepage extender is used to solve the problem of insufficient creepage of the original porcelain pillar insulator, which can prevent the tripping accidents caused by pollution flashover and condensation flashover;

7. Solve the problem of phase-to-phase insulation of the bus duct.
