High voltage cable clamps have found a number of advantages during the first few years of production and operation. Due to the high mechanical strength of the surface layer of the High voltage cable clamp, cracks are less likely to occur on the surface. The electrical strength of the glass generally remains constant throughout the operation, and the aging process of the High voltage cable clamp is much slower than that of porcelain. Therefore, the High voltage cable clamp is mainly scrapped due to self-damage, which occurs within one year of operation, but the porcelain high voltage cable The defects of clamp are only discovered after a few years of operation.
The material used to manufacture the High Voltage cable clamp is more stable than the raw material used for the manufacture of the electric porcelain, and creates favorable conditions for stabilizing the electrical and mechanical properties of the glass. Due to the transparency of the glass, it is easy to find small cracks and various internal defects and damages during the shape inspection. The electromechanical properties of tempered glass are much higher than those of porcelain, and the same type of High voltage cable clamp is manufactured, and the High voltage cable clamp is much smaller in size and weight than the porcelain High voltage cable clamp.
