Abstract
The invention relates to a composite anti-puncture power cable, which includes a conductor, the outer side of the conductor has a first conductor shielding layer, the outer side of the first conductor shielding layer has an insulating layer, and the outer side of the insulating layer has a second conductor The shielding layer, the outer layer of the shielding layer of the second conductor is wrapped with a protective layer. The composite anti-puncture power cable of the present invention adopts double-layer conductor shielding materials, and the raw materials for conductor shielding are relatively easy to obtain. By adding nano-scale lead-metal compounds, the volume resistivity can be reduced. The lower the volume resistivity, the better the conductivity of the shielding material The shielding performance of the cable is also good, and the breakdown resistance of the cable is significantly improved.
Description
Technical field [0001] The present invention relates to a composite anti-wear power cable. Background technique [0002] The main cause of cable insulation breakdown has mechanical damage, insulation, insulation, cable head fault, overvoltage, etc., specific, may include the following aspects: (L) Mechanical damage. In the cable insulation, the proportion of mechanical damage is large, and the common causes are as follows: L) Direct affected by external force, such as heavy objects falling down from high, excavation, accidental injuries, etc. 2) When the cable is bent, the cable is bent over ambassador, and the cable is severely squeezed to damage the insulation and protective layer. 3) The direct buried cable is subjected to excessive pressure due to the stratum sink, resulting in damage to insulation, and even disconnecting the cable. (2) Insulation aging. During the long-term operation of the cable, the mountain is too high, causing the electrical properties and mechanical pro...
