Abstract

The invention discloses a high-voltage buried cable, which comprises a conductive cable core, wherein an insulating layer, a first armor layer, a waterproof sheath layer, a second armor layer, an inner sheath layer, a third armor layer and an outer sheath layer are sequentially arranged outside the conductive cable core from interior to exterior; the inner sheath layer is a sheath layer with deratization agents; and the outer sheath layer is a wear-resistant waterproof sheath. Due to the mode, the high-voltage buried cable has good waterproof effect and enough strength, can relieve the destructiveness of the cable to a certain degree and is durable in use; and additionally, the high-voltage buried cable has the function of preventing damaged caused by rats.

Description

technical field [0001] The invention relates to the field of cables, in particular to a high-voltage buried cable. Background technique [0002] High-voltage cable is a kind of power cable, which refers to the power cable used to transmit between 10KV-35KV (1KV=1000V), and is mostly used in the main road of power transmission. Some main road high-voltage cables need to be laid underground, and the cables are required to have good waterproof performance. Due to urban construction, it is often encountered that excavators dig into buried cables and damage the cables to cause power outages. Therefore, buried cables are required to have sufficient strength to slow down this damage. In addition, the existing buried cables do not have the anti-rat bite function. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a high-voltage buried cable, which can solve the defects in the prior art, has good waterproof effect, and ha...
