Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides the following technical solutions: the utility model provides a cold-resistant power cable of tensile, includes outer 1 of rubber, rubber inlayer 2 and sinle silk 3, and rubber inlayer 2 is provided with four altogether, and sinle silk 3 is located the inside of rubber inlayer 2, and rubber inlayer 2 is located the inside of outer 1 of rubber, is provided with limit structure 8 between four rubber inlayer 2, and limit structure 8 can guarantee that the skew can not appear in the electric wire, and limit structure 8 includes rubber trunk 4 and stopper 5.

Further, the surface of rubber inlayer 2 is provided with rock wool layer 6, and rock wool layer 6 can guarantee the cold-resistant effect of cable, and rock wool layer 6's surface is provided with protective sheath 11, is provided with tensile subassembly 10 between protective sheath 11 and the rubber skin 1, and tensile subassembly 10 can increase the tensile effect of cable, prevents the cable disconnection, and tensile subassembly 10 includes outer lane 7 and inner circle 9.

Further, rubber trunk 4 is located the inside centre on rock wool layer 6, and stopper 5 is located 4 outer surfaces of rubber trunk, can be effectual carry on spacingly to the electric wire.

Specifically, the surface of stopper 5 cooperatees with the surface of rubber inlayer 2, and stopper 5 is provided with a plurality of altogether, and stopper 5 can be spacing whole section electric wire, guarantees that the electric wire is more stable.

It is worth mentioning that the inner ring 9 is located on the inner wall of the rubber outer layer 1, and the outer ring 7 is located on the outer wall of the protective sleeve 11, so that the tensile property of the cable can be increased through the inner ring 9 and the outer ring 7.
