Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a corrosion resistant cable for petrochemical, includes special-shaped separator 1, special-shaped separator 1 is anticorrosive rubber material, and as rubber, it itself has certain elasticity, 1 lateral surface of special-shaped separator is opened in proper order has first draw-in groove 2 and second draw-in groove 3, first draw-in groove 2 and second draw-in groove 3 are the arc wall, and first draw-in groove 2 and second draw-in groove 3 cross arrangement. The number of the first clamping grooves 2 and the number of the second clamping grooves 3 are 3, the first clamping grooves 2 and the second clamping grooves 3 are arranged adjacently, the insulating sleeve 4 is arranged in the first clamping groove 2, the conductor 5 is arranged on the inner side of the insulating sleeve 4, the core filling sleeve 6 is arranged in the second clamping groove 3, and the core filling sleeve 6 and the insulating sleeve 4 are both tangent to the inner side surface of the inner bushing 7. And the core filling sleeve 6 is a polypropylene molding filling strip. The polypropylene has higher heat resistance, the continuous use temperature can reach 110-120 ℃, and the polypropylene has good mechanical property, besides impact resistance, good insulating property, better other mechanical properties than polyethylene and good forming and processing properties. When the cable receives the pulling force, make pulling force to fill core cover 6 dispersion through dysmorphism separator 1, reduced the destructive power that causes the conductor when dragging to reach the effect that improves cable life.
