High Voltage Electrical Cable

Introduction

A high voltage electrical cable is a kind of power cable, which is used to transmit power between 1kv and 1000kv. It is mostly used for power transmission and distribution. The components of high-voltage cable from inside to outside include: conductor, insulation, inner sheath, filler (armor), and outer insulation. Of course, the armored high-voltage cable is mainly used for burying, which can resist high-strength compression on the ground and prevent other external force damage.

Definition

1. Most of the high-voltage distribution lines in the 10kV urban area use insulated sheathed conductors, but even if there are insulated sheaths, high-voltage lines need to use one or several porcelain bottles to insulate poles or iron towers.

2. 35kV and above high-voltage transmission lines use bare conductors, and more porcelain bottles are used for insulation due to different voltage levels. You can see this directly by observing the lines around you.

3. Due to different pollution levels in different regions, the number of porcelain bottles in the porcelain string of lines with the same voltage level in different regions is also different. 110 kV 7 pieces; 220kV13 pieces; 330kV17 pieces; 500kV25 pieces.

Characteristics

High voltage electrical cable adopts a high-frequency voltage doubling circuit, takes the lead in applying the latest PWM high-frequency pulse width modulation technology, makes closed-loop adjustments, and adopts large voltage feedback to greatly improve the voltage stability. Use high-power IGBT devices with excellent performance and their driving technology, and take special shielding, isolation, and grounding measures according to the electromagnetic compatibility theory. The cable detector is of high quality and portable and can withstand rated voltage discharge without damage.

Advantages

1. Increase the conveying capacity.

2. Increase the stability limit.

3. Reduce line consumption.

4. Reduce project investment.

5. Save the corridor area.

6. Improve the power grid structure.

Application

The high voltage electrical cable is the bridge between power supply equipment and electrical equipment, which can play the role of transmitting electric energy. Moreover, high-voltage cables are widely used, such as the military, aerospace, and other fields.
