Abstract

The utility model discloses a mica lapped cable. An inner glass fiber insulation layer, a mica tape, and an outer glass fiber insulation layer which are good insulation and high temperature resistance are sequentially lapped on the periphery of the outer side of a conductor from inside to outside, wherein the conductor is formed by stranding a plurality of copper cores, thus the cable can resist the high temperature of 500-800 DEG C and be applied to some high temperature environments. Simultaneously, the inner glass fiber insulation layer, the mica tape and the outer glass fiber insulation layer are not easily aged and the using safety of the cable in high temperature conditions is improved.

Description

Mica wrapped cable

technical field

The utility model relates to a mica wrapping cable.

Background technique

In some electrified cables, a copper core is often used as a conductor, and then a silicone insulating sheath is wrapped on its outer circumference. However, this kind of energized cable has a low degree of heat resistance during work, which cannot meet the needs of some high-temperature application environments. Moreover, the insulating sheath made of silicone insulating materials is prone to aging at relatively high temperatures, which affects the performance of the cable. safety of use.

Contents of the invention

The purpose of the utility model is to provide a mica-wrapped cable with high temperature resistance, so as to meet the use requirements under some high temperature application conditions.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a mica-wrapped cable, the cable includes a conductor composed of multiple strands of copper core twisted, and the outer circumference of the conductor is wrapped with inner glass fiber insulation layer, a mica tape is helically wound on the outer peripheral portion of the inner glass fiber insulating layer, and an outer glass fiber insulating layer is also wrapped on the outer peripheral portion of the mica tape.

Preferably, the inner glass fiber insulation layer and the outer glass fiber insulation layer are respectively in the shape of a woven mesh.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art: In the mica-wrapped cable of the utility model, the outer periphery of the conductor formed by twisting multiple strands of copper cores is The inner glass fiber insulation layer, the mica tape and the outer glass fiber insulation layer with good insulation and high temperature resistance are wrapped in sequence, and the obtained cable can withstand high temperatures of 500°C to 800°C, which makes the cable suitable for In some high-temperature environments, at the same time, the inner glass fiber insulation layer, mica tape, and outer glass fiber layer are not easy to age, which improves the safety of the cable under high temperature conditions.

Description of drawings

Accompanying drawing 1 is the cross-sectional structure diagram of the mica wrapping cable of the present utility model.

Detailed ways

The technical solution of the present utility model will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

Referring to the mica-wrapped cable shown in FIG. 1 , the cable includes a conductor 1 formed by twisting multiple strands of copper wires. The outer circumference of the conductor 1 is wrapped with an inner glass fiber insulation layer 2, the outer circumference of the inner glass fiber insulation layer 2 is spirally wound with a mica tape 3, and the outer circumference of the mica tape 3 is wrapped with an outer glass fiber insulation layer 4. The inner glass fiber insulating layer 2 and the outer glass fiber insulating layer 4 are braided mesh structures formed by weaving glass fiber tapes respectively. Due to the good insulation and high temperature resistance of glass fiber and mica tape materials, the mica wrapped cable can withstand high temperatures of 500 ° C to 800 ° C, which makes the cable suitable for some high temperature environments. At the same time, The inner glass fiber insulation layer, mica tape, and outer glass fiber layer are not easy to age, which improves the safety of the cable under high temperature conditions.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present utility model, and its purpose is to enable those familiar with this technology to understand the content of the present utility model and implement it accordingly, and not to limit the protection scope of the present utility model. All equivalent changes or modifications made according to the spirit of the utility model shall fall within the protection scope of the utility model.
