Embodiment Construction

[0021] The structure of the weather-improved thread of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the weather-improved wire includes a conductor 1 extruded on the outer layer of the conductor 1 with an insulating layer 2 and a sheath 3 wrapped around the outer layer of the insulating layer 2. The wire 1 is a single wire, and the wire 1 is a single wire. The insulating layer 2 is made of weather-resistant polyvinyl chloride material, and the sheath 3 is made of low-density polyvinyl chloride added with a light shielding agent.

[0023] The weather-resistant polyvinyl chloride is prepared by adding 35-40 parts of tricresyl phosphate to polyvinyl chloride.

[0024] The light shielding agent is carbon black.

[0025] The conductor is copper wire or aluminum wire.

[0026] The following table (table 1 / table 2) shows the type, size and performance of the copper core wind and rain impro...

Abstract

The invention discloses a weather-proof improved wire which comprises a conductor, an insulation layer and a sheath. The insulation layer is extruded on the outer layer of the conductor, and the sheath wraps the outer layer of the insulation layer. The conductor is a single lead wire, the insulation layer is made of weather resistance polyvinyl chloride materials, and the sheath is made of low-density polyvinyl chloride added with a light screening agent. The weather-proof improved wire has the advantages of being small in power consumption, long in service life, capable of being not easily pulled broken, resistant to ageing, not prone to electric leakage and the like.

Description

technical field [0001] The invention relates to the field of electric wires and cables, in particular to a wind and rain improved wire. Background technique [0002] The wind and rain line is also called the black leather line. At present, wind and rain wires are mostly made of polypropylene filaments coated with a conductor core covered with a rubber layer, and finally covered with asphalt, which has the advantages of sun resistance and waterproof. However, due to its complicated manufacturing process and high price, it has been gradually replaced by anti-aging wires. [0003] In addition, most of the user's outdoor wires use unsheathed cables for fixed wiring, which has many shortcomings: 1. Poor voltage stability and large voltage loss, which is not conducive to saving electric energy; 2. Many insulating fittings (porcelain bottles) and supporting fittings (cross arm) are required , electric poles, pull wires, etc. for auxiliary installation, complex construction, low e...
