Problems solved by technology

The advantage is that the processing technology is simple, the disadvantage is that it is not fire-resistant, and the working temperature is low, generally only 65~105°C
Polyvinyl chloride insulation contains chlorine, which produces toxic gas when burned, which causes serious harm to the human body and pollutes the environment. It is currently being phased out.
Ceramic insulation is a brand-new new material in the cable industry, but the ordinary ceramic insulation structure brings hidden dangers to cable laying due to its low compressive strength

Embodiment Construction

[0014] Such as figure 1 As shown, a hole-shaped reinforced ceramic insulated electric control composite cable according to the present invention includes a power cable conductor reinforcing hole 5 arranged in the center of the cable and a ceramic insulating layer 2 extruded outside the power cable conductor reinforcing hole 5; The power cable conductor reinforcement hole 5 is provided with a power cable conductor 1; the ceramic insulating layer 2 is provided with a circle of control cable conductor reinforcement holes 4 at equal intervals, and each control cable conductor reinforcement hole 3 is correspondingly provided with a control cable conductor 4. The inner diameter of the reinforcing hole 5 of the cable conductor is equal to the outer diameter of the power cable conductor 1, and the inner diameter of the reinforcing hole 3 is larger than the outer diameter of the control cable conductor 4. The thickness of the ceramic insulating layer 2 is 2-3 times of the outer diamete...

Abstract

The invention discloses a hole-shaped enhanced ceramic insulating electric-control composite cable which comprises a power cable conductor enhancing hole and a ceramic insulating layer extruded outside the power cable conductor enhancing hole. A power cable conductor is arranged in the power cable conductor enhancing hole, a circle of control cable conductor enhancing holes are equidistantly formed in the ceramic insulating layer, a control cable conductor is correspondingly arranged in each control cable conductor enhancing hole, inner diameter of each cable conductor enhancing hole is equal to outer diameter of the power cable conductor, and inner diameter of each enhancing hole is larger than outer diameter of each control cable conductor. The hole-shaped enhanced ceramic insulating electric-control composite cable has the advantages of high chemical stability, oxidation resistance, acid resistance, alkali resistance, high insulating mechanical strength, extrusion resistance, convenience in laying and the like.

Description

[0001] technical field [0002] The invention belongs to the field of power cables, and in particular relates to a hole-shaped reinforced ceramic insulated electric control composite cable. Background technique [0003] At present, most of the plastic insulation materials for domestic cables are XLPE and PVC, namely cross-linked polyethylene and polyvinyl chloride. The advantage is that the processing technology is simple, and the disadvantage is that it is not fire-resistant and the working temperature is low, generally only 65~105°C. Polyvinyl chloride insulation contains chlorine, which produces toxic gas when burned, which causes serious harm to the human body and pollutes the environment. It is currently being phased out. Ceramic insulation is a brand-new new material in the cable industry, but ordinary ceramic insulation structures bring hidden dangers to cable laying due to their low compressive strength. Contents of the invention [0004] The technical problem to...
