Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Such as figure 1 As shown, a shielded monitoring cable according to the present invention includes a conductor, and the conductor is composed of a spandex fiber bundle 1 in the middle and an oxygen-free copper wire bundle 2 wrapped outside the spandex fiber bundle 1. An inner shielding layer 3 is arranged outside the conductor, an inner insulating layer 4 is arranged outside the inner shielding layer 3, an outer shielding layer 5 is arranged outside the inner insulating layer 4, and an outer shielding layer 5 is arranged outside the outer shielding layer 5. Insulating layer 6, the inner shielding layer 3, inner insulating layer 4, outer shielding layer 5 and outer insulating layer 6 are co-extruded from four layers, the conductor, inner shielding layer 3, inner insulating layer 4, outer shielding layer 5 Form a conductive unit with the outer ins...

Abstract

The invention relates to a shielded monitoring cable, which comprises conductors, and is characterized in that each conductor is externally provided with an inner shielding layer, the inner shielding layer is externally provided with an inner insulating layer, the inner insulating layer is externally provided with an outer shielding layer, the outer shielding layer is externally provided with an outer insulating layer, conductive units are externally provided with a filled layer, the filled layer is externally provided with a non-woven fabric wrapping layer, the non-woven fabric wrapping layer is externally provided with aramid fiber and copper wire braiding shielded monitoring layer, the aramid fiber and copper wire braiding shielded monitoring layer is internally provided with monitoring wire core units, each monitoring wire core unit is composed of a monitoring wire core and an aramid fiber braiding layer, the aramid fiber and copper wire braiding shielded monitoring layer is externally provided with an outer sheath layer, and the diameter of each conductive unit occupies 1 / 4 of the diameter of a cable body. The shielded monitoring cable is good in conductivity, high in overall strength, not only capable of monitoring, but also capable of shielding, and high in stability.

Description

technical field [0001] The invention relates to a cable, in particular to a monitoring cable. Background technique [0002] With the rapid development of the national economy, as the main artery of the national economy, the amount and scope of wire and cable are increasing. In recent years, power plants, substations, smelting and petrochemical industries have a great demand for cables. The use of cables for mining shearers is also increasing, and the country is paying more and more attention to the safe use of mining cables. Therefore, it is an effective method to manufacture a new type of shielded monitoring cable to solve the current instability, poor strength performance, insufficient monitoring performance, and poor flexibility of common mining shielded monitoring cables. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the deficiencies in the prior art and provide a shielded monitoring cable with good electrica...
