Abstract

The invention discloses a waterproof fireproof control cable comprising a rubber skeleton, wherein the rubber skeleton comprises four circular skeletons with different radiuses; the left side surfacesof the four circular skeletons are fixedly connected together and then the four circular skeletons are successively stacked according to the radiuses; first wire cores are disposed in the four circular skeletons; a plurality of second wire cores are disposed in each of the second circular skeleton, the third circular skeleton and the fourth circular skeleton; each first wire core includes a firstconductor; and the outer side of the first conductor is successively coated with a thermoplastic vulcanized rubber insulating layer and a halogen-free glass fiber wrapping layer. The outer side of the rubber skeleton is successively coated with a glass fiber belt and ceramic silicone rubber belt wrapping layer, a lead alloy inner sheath layer, a waterproof expansion filling layer and an outer sheath. Thus, the cable is good in waterproof and fireproof effect, simple in structure, good in insulation effect, long in service life, stable in operation and low in production cost. An ethylene propylene rubber elastic rod enhances the softness of the cable.

Description

technical field

[0001] The invention relates to the technical field of cables, in particular to a waterproof and fireproof control cable. Background technique

[0002] The existing fireproof cables have complex processes and high costs. At the same time, the manufacturing length is also limited; in addition, the cable is easy to absorb moisture, and after moisture absorption, the moisture will penetrate longitudinally along the cable, resulting in a decrease in the insulation performance of the cable and affecting the electrical performance. In addition, the cable has poor bending performance and is easy to break. Contents of the invention

[0003] The object of the present invention is to provide a waterproof and fireproof control cable in order to remedy the defects of the prior art.

[0004] The present invention is achieved through the following technical solutions:

[0005] A waterproof and fireproof control cable, including a rubber skeleton, the rubber skeleton i...
