Description
Technical field
The utility model relates to cable, specifically the buggy ladle private cable.
Background technology
At present, widely used buggy ladle cable mainly is conductor with the fine copper, and natural+butylbenzene mixed rubber is the traditional handicraft of insulation and sheath material.China is the first in the world big steel country, buggy ladle cable demand is huge, the cable environment for use is very special, abominable, bear very big pulling force and ambient temperature is high, can occur at any time in using molten steel spatter boiling hot, slag collides with, cable car stretches, surface wear, internal break situation, cause cable to damage in various degree even scrap.The traditional cable conductor structure is single, tensile strength is low; Insulation and sheath material mechanicalness, tear resistance, resist subdue, elasticity and poor processability; Oxytolerant and ozone resistance are poor, aged deterioration easily; Oil resistant and poor solvent resistance, the corrosive power of antiacid alkali is low; Thermal endurance is low, and is combustible material.Therefore, generally can only move about three days untimely solution in case cable goes wrong, molten steel just can not in time be transported to assigned address, and molten steel and buggy ladle will be set in together, not only causes very big waste to resource, and consequence is very serious, and economic loss is huge.
The utility model content
The purpose of this utility model is the defective that exists at prior art, the buggy ladle private cable is provided, be a kind of structure uniqueness, material rationally, craft science and can effectively increase work efficiency, the buggy ladle private cable of product quality and energy savings, have the characteristics of stretching resistance, high temperature resistance, anti-tear mill.
The technical scheme that its technical problem that solves the utility model adopts is: buggy ladle private cable, its structure comprise outside protective sleeve and protective sleeve conductor inside core; Described conductor thread core by the stretching resistance of centre strengthen inner core and around inner core its peripheral copper bunch core is stranded constitutes.
