IEC60502 450 / 750V Shielded Vfd Customized Wire And Cables

VFD Variable Frequency Wires and Cables

with Low Voltage or Medium Voltage.

PRODUCTS DESCRIPTION

VFD Variable Frequency Wires and Cables with Low Voltage or Medium Voltage, the structure of frequency conversion cable includes three main line insulation wires and three zero line insulated wires. The inner wrapping layer, copper tape layer, outer winding cladding layer and outer sheath layer are set outside the main line insulation line and the zero line insulation line in turn to form a 3 + 3 core structure, which makes the cable have strong voltage resistance, can withstand the pulse voltage of high-speed frequent frequency conversion, and has a good protection effect on the frequency conversion electrical appliances.

PRODUCTS KEY-WORDS

VFD Frequency Cables, Frequency Conversion Cables, Frequency Transformer Cables, Frequency Converter Cables.

PRODUCTS APPLICATION

VFD Variable Frequency Wires and Cables with Low Voltage or Medium Voltage, it is mainly used for the connection between the frequency conversion power supply and the variable frequency motor, as well as in the power transmission and distribution lines with the rated voltage of 1kV and below. It can keep the frequency converter in normal operation without electromagnetic interference, It is especially suitable for electric power, environmental protection, petroleum, chemical industry, coal mine, railway, pharmacy, mining equipment, metallurgy and steel, network communication, equipment manufacturing, paper industry and other industries.

PRODUCTS CHARACTERISTIC

VFD Variable Frequency Wires and Cables with Low Voltage or Medium Voltage, it has the below characteristic:

1. The influence of pulse voltage on Insulation: the frequency regulation range of frequency conversion power supply is wide. No matter the frequency is high or low, it has a main frequency waveform profile, which contains many high-order harmonics. As a traveling wave, after multiple reflection, the amplitude superposition can reach several times of the working voltage. The longer the cable is, the higher the amplitude is. If the cable insulation safety factor is not high, it may be broken down.

2. The cable body emits electromagnetic wave to the outside: generally, the frequency conversion household appliances are single-phase power supply with short length and small power. The variable frequency power supply, connecting cable and frequency conversion motor are set in the metal shell to suppress the electromagnetic wave emission. However, in the industrial field, the motor power is large, and the length of the cable connecting the variable frequency motor and the variable frequency power supply is long. During the operation, the cable is an effective carrier for the high-frequency electromagnetic wave to transmit outward, which will cause great interference to the broadcasting communication in the surrounding areas, and sometimes the situation is more serious, which is called the environmental pollution of electromagnetic wave.

3. Superposition of neutral line current: in a complete three-phase sinusoidal power supply system, when the three-phase current is balanced, the neutral line current is zero. If the third harmonic appears, the current component of the third harmonic has no phase difference in the neutral line, so the direct superposition component is three times. If the original power supply objects of frequency conversion are three single-phase variable frequency motors, and the three-phase power distribution is balanced, the neutral line current is larger, and the neutral line cross-section should not be less than the phase cross-section.
