Briefly explain the difference between variable frequency cable and other cables
- Oct 24, 2018 -

Those who are familiar with the inverter cable should know that this is a connection device that is widely used on the inverter mainframe. However, some other properties of the inverter cable may not be known. So what is the difference between the inverter cable and the ordinary cable?

1, the voltage is different

The voltage values used for ordinary cables are not oriented and are generally ultra-high pressure. Different frequency conversion cables, the commonly used voltage values are generally Central Asia and low voltage, the more common voltage values are 0.6 kV, 10 kV and 16 kV, etc.;

2, the structure is different

The ordinary cable adopts the extrusion extrusion structure in the structural design, and basically has no shielding performance on the inner core. The variable frequency cable has been innovative in the common cable structure, adopting a parallel arrangement structure, and also has a shielding layer to ensure the cable has anti-interference performance in use. At the same time, in the design of the insulation layer, high-strength extrusion type is adopted, which is not the same as extrusion extrusion, and the structure design is more clear. In addition to the inner core and the protective layer, the outer layer of the cable is also added. Layer protection sleeve for deep protection.

3, different uses

Inverter cables and ordinary cables are similar in their use. They are all conducting electrical energy. However, ordinary cables have certain limitations in power transmission because of limited structural design, especially in the use of variable frequency motors. In comparison with the change of current during the operation of the motor, the frequency conversion cable can be a dedicated cable of the variable frequency motor in this respect, and can be used not only as a connection line but also as a wire for transmitting electrical energy.

4, different interference

Ordinary cables sold on the market generally have no interference performance. This is mainly determined by the difference in cable structure design. This has obvious advantages in the frequency conversion cable. As a special cable for variable frequency motors, the interference performance is the basic condition. Especially in the environment with strong magnetic field, it can ensure the stability of the frequency conversion host to achieve power transmission;

5, different models

Normally, the common cable is mainly based on the general model, and the inverter cable may be more abundant in the model.
