Problems solved by technology

Frequency conversion cables are often used in harsh working conditions, and the frequency conversion cables are often required to have good oil resistance to prevent oil from corroding the frequency conversion cables. Due to oil immersion, the surface of the frequency conversion cables is cracked, affecting the performance of the frequency conversion cables, resulting in The interruption of frequency conversion cable transmission will cause short circuit of electrical appliances, resulting in damage to electrical appliances, resulting in shortened service life of frequency conversion cables

Abstract

According to the variable frequency cable preparation method, a cable core, a belting layer, a metal shielding layer, an isolation sleeve layer, an armor layer and an outer sheath layer prepared from an oil-resistant sheath material are included, and the cable core, the belting layer, the metal shielding layer, the isolation sleeve layer, the armor layer and the outer sheath layer are sequentially arranged from the center to the outside; the raw materials of the oil-resistant sheath material comprise PVC resin powder, fluorosilicone resin and dispersed polytetrafluoroethylene resin. The variable-frequency cable prepared by the preparation method of the variable-frequency cable meets various index performance conditions of the national standard of cable sheath materials, and the oil resistance of the variable-frequency cable is improved due to the fact that the outer sheath layer contains the PVC resin powder, the fluorosilicone resin and the dispersed polytetrafluoroethylene resin.
