Waterproof agricultural buried cable

Abstract

The invention discloses a waterproof agricultural buried cable, which relates to the field of electric wires and cables. The waterproof agricultural buried cable comprises a conductor which is surrounded and wrapped by an insulating layer and a protective layer from inside to outside sequentially. The cable is characterized in that: the conductor is a compacted conductor without a single-wire gap, is surrounded and wrapped by a waterproof layer between the insulating layer and protective layer and also has longitudinal and radial waterproof structures. The waterproof structures arranged on the cable can effectively prevent water from radially entering the insulating layer of the cable, also prevent the water from axially permeating the cable and greatly improve the insulating property and the problems of high leakage, heavy loss, easy breakdown and power-failure and the like of the product, thereby greatly prolonging the service life of the cable and ensuring power supply safety. Thus, the waterproof structures arranged on the cable plays an important role in fulfilling the aim of upgrading rural power grids to be safe, high in quality, highly-efficient and low in consumption.

Description

【Technical field】 [0001] The invention relates to the field of electric wires and cables. 【Background technique】 [0002] The existing agricultural direct-buried cables are basically produced according to the JB / T2171_1999 standard, which was formulated by the former Ministry of Electric Power in the 1970s. Although it has been revised many times, the content has basically remained unchanged. At that time, in order to reduce product costs , The cable conductors are all made of aluminum conductors, and the structure is simple. These cables have problems such as easy corrosion of the conductors, easy broken cores, and easy moisture in the insulation. Often due to power outages and leakage of electricity, the agricultural machinery cannot operate normally, and the electricity consumption of farmers cannot be guaranteed, sometimes endangering the safety of people and animals. The grid power supply has poor reliability, poor power quality, high energy consumption, and unsafe ele...

[0002] The existing agricultural direct-buried cables are basically produced according to the JB / T2171_1999 standard, which was formulated by the former Ministry of Electric Power in the 1970s. Although it has been revised many times, the content has basically remained unchanged. At that time, in order to reduce product costs , the cable conductors are all made of aluminum conductors, and the structure is simple. These cables have problems such as easy corrosion of the conductors, easy core breakage, and easy damp insulation.

Often due to power outages and leakage of electricity, the agricultural machinery cannot operate normally, and the electricity consumption of farmers cannot be guaranteed, sometimes endangering the safety of humans and animals.

Power grid power supply reliability is poor, power quality is poor, energy consumption is high, power consumption is unsafe, and it is impossible to achieve the goal of safe, high-quality, high-efficiency, and low-consumption rural power grid transformation

Although some people have proposed to replace aluminum conductors with copper conductors and improve the water-blocking performance, there are still problems such as expensive products and poor water-blocking effects.
