Abstract

The invention relates to an antistatic and ultrahigh-voltage silicone rubber cable. The cable comprises conductors and insulating layers, wherein the insulating layers wrap the conductors. The insulating layers are extruded by inner sheaths. First drainage covers wrap the inner sheaths used for protecting the insulating layers and the conductors. Wire core sheaths wrap the first drainage covers and are stranded to form a cable core. A shielding layer, a second drainage cover, a breakdown-resistant layer and an outer sheath sequentially wrap the cable core from inside to outside. The cable has the advantages of being reasonable in structural design, long in service life, good in voltage withstand performance and the like. The first drainage covers, the second drainage cover and the wire core sheaths are combined, so that the antistatic performance of the cable is improved, and the electrostatic phenomenon inside the cable is fully avoided. Through the breakdown-resistant layer, the voltage withstand performance of the cable is improved, and the service life of the cable is prolonged.
