Product name: Porcelain post insulators/ High voltage post insulator C6-1550
Material: Alumina and silica porcelain
Application: Electricity transmission and transformation
meet outdoor usage requirements.
Station post insulator is used for insulation and connection between conductive body and grounding body, it consists of porcelain body and top bottom fitting.
CLD's insulator is alumina ceramic post insulator. The product mainly consists of alumina and silica.It has high dielectric properties and great mechanical performance.
CLD has advanced management experience, production flow and quality control means to provide customers with guaranteed high-quality products.
Providing a low price by controlling the raw materials and manufacture process;
Different glaze protects the insulator's surface from pollution and improves strength to meet outdoor usage requirements.
Metal fittings are all made from ductile iron or malleable iron, and all fittings are hot-galvanized to get zinc layer.
CLD has 500 employees and covers an area of 18000 square meters,and has 4 insulator production lines for dry process, 2 international most advanced insulator production lines for iso-static process and 1 line for composite insulator. Now CLD is the largest line post porcelain insulator manufacturers in china and the largest high-voltage post insulator manufacturer worldwide.
CLD has a group of technical and engineering people who help us keep innovating, and now CLD has 21 patents and a national porcelain test center. So CLD can produce and test reliable products to international standards such as IEC､ANSI､BS､DIN､AS.
