Copper braided tape soft connection straightening is the premise of copper bar use

In the process of installing the transformer, the copper braided tape is used in the pile head, and the copper bar is connected at the back. In order to simplify the process and save materials, we put forward a bold idea, that is, can the copper soft connection not bend, directly use the length of the copper braided belt soft connection as the length of the copper bar connection during installation, without losing the performance and role of the soft connection.

After practice, this idea is completely feasible, because the soft connection is to make up for some applications that the hard bus can not achieve. However, it is necessary to consider that the electrical safety distance of the copper braided tape soft connection in the loop must meet the electrical safety requirements.

Not only that, the swing amplitude of the copper braided belt soft connection should be able to meet the requirements of the safety distance when the dynamic stability, that is, when there is a large fault current through the copper soft connection, the electrical power generated will make the conductor swing or vibration, at this time to meet the safety distance.

In the process of straightening the copper braided soft connection as a copper bar, it is also necessary to consider that the allowable stress of the transformer pile head and the other conductor can be determined according to the direction of the copper soft connection. Of course, if it is not pulled very straight, the stress is negligible.

At present, there are two main manufacturing processes of copper braided tape soft connection. One is to take the braided tape as a conductive wire in the traditional way, and cover the copper tube at both ends to make it; The other is the use of welding equipment, through high temperature melting pressure.

Copper braided belt soft connection is mainly used for non-horizontal charged movement, as well as high and low voltage circuit breakers and machine tools as cables, hardware, power components used, its price mainly depends on the current price of copper and braided belt specifications, in short, it is certainly a point of the price of goods.
