This product is suitable for high-voltage transmission lines and facilities. With good hydrophobicity, aging resistance, resistance to tracking resistance and electrical erosion resistance, with high tensile strength and flexural strength, high mechanical strength, impact resistance, shock and anti-brittle fracture of good performance , weight management light, easy to install, its top and bottom mounting dimensions and corresponding installation of porcelain pin the same size, can be used interchangeably. This product is suitable for urban and technological innovation, can effectively use the narrow corridor area of ??the city boost power transmission, can reduce the tower height, because of its high flexural strength, transverse rupture accident prevents porcelain Tam prone, and good stain resistance .

When (2) product lifting, fight knot on the end attachments, is strictly prohibited hit the umbrella group or jacket, rope must touch base with the jacket and umbrella parts, should contact parts with a soft cloth. (3) non-insulator foot umbrella group. (4) Do not put the line composite insulators as aids to avoid it by impact or bending damage insulators. (5) Installation equalizing ring, you should pay attention to adjust the equalizing ring and vertical mounting axis, for open-type equalizing ring, attention should be open at both ends in the same direction, in favor of the discharge and the umbrella group. Generally speaking routine, 110kV - string insulator string has eight, but in 1000 meters above the high altitude of 40 meters above the tower, there is a very serious filthy place, would be appropriate to increase the number of insulators according to regulations.
