Problems solved by technology

[0002] With the intensification of competition in the market economy, energy saving and consumption reduction are imperative for the cable industry to meet its own development needs. The frequency converters that came out in the early 1980s have many advantages such as low noise, long life, small size, large capacity, and energy saving. The advantages are widely used in metallurgy, electric power, petrochemical, textile and other fields. The frequency conversion cable used as the frequency conversion current and the connection line of the frequency converter will be affected by the high-order harmonics generated by the frequency converter when the frequency converter is working. The current frequency converter on the market Most cables have a 3+1 structure. When high-order harmonics are generated, after multiple reflections of the cable, there will often be opportunities for peaks to peaks or troughs to be superimposed, and the cable itself acts as a capacitor to amplify high-order harmonics. role, so it is easy to be broken down by high-frequency pulse current

Abstract

A crosslinked polyethylene Insulated copper wire copper strip shielding frequency converter cable comprises a cable core, a copper wire shielding layer wrapped on the cable core, a shielding layer wrapped on the copper wire shielding layer and an outer sheath layer arranged outside the shielding layer. Main conductors, an insulating layer I, secondary conductors and an insulating layer II are extruded to form the cable core, secondary conductors are symmetrically distributed at the two sides of the main conductors, and copper wires are woven and lapped to form the copper wire shielding layer. The crosslinked polyethylene insulated copper wire copper strip shielding frequency converter cable in the invention is not liable to strike through by a high frequency pulse current, and has good shielding performance and is less susceptible to electromagnetic wave interference.

Description

technical field [0001] The invention relates to a power cable, in particular to a cross-linked polyethylene insulated copper wire copper tape shielded inverter cable. Background technique [0002] With the continuous intensification of market economic competition, the cable industry needs to save energy and reduce consumption for its own development needs. The inverters that came out in the early 1980s have many advantages such as low noise, long life, small size, large capacity, and energy saving. The advantages are widely used in metallurgy, electric power, petrochemical, textile and other fields. The frequency conversion cable used as the frequency conversion current and the connection line of the frequency converter will be affected by the high-order harmonics generated by the frequency converter when the frequency converter is working. The current frequency converter on the market Most cables have a 3+1 structure. When high-order harmonics are generated, after multiple ...
