Tangshan Porcelain Insulator company Co., Ltd which is built in 1952, the predecessor is “Tangshan High Voltage Porcelain Factory”. In 2003 it succeeded the remanufacture is the limited liability company, the establishment “the Tangshan city porcelain insulator limited company”. It is the biggest rod insulator enterprise in China. As a professional porcelain insulator company, it concentrates on the development, design, and manufacturing of 126kV~1100kV rod insulator, ±500kV、±800kV DC rod insulator and 126kV~550KV SF6 porcelain shell etc. High quality, wide range of products and high working efficiency make it is one of the key enterprises in China insulator industry. The product trade mark is “TD”.
The company's current product manufacturing equipment, product testing means and quality have a leading position in the national industry; the leading products of 110 kV and the above rod post insulators covered 33.01% in the domestic market, ranking the first among the national industries.
The company is the first one that has gained the Adoption of International Standards certificates and the Adoption of International Standards Product Sign certificate. The production of 110 KV ~ 110 KV and 1100 KV rod insulators ~ 550 KV casing products, all are adopted IEC standards, standards and enterprise standard and strict according to the standards and the rules for the Inspection of the enterprise examination.
Products of the company have a high reliability small margin and large dispersion, widely used in 126 kV-1100kV substation as isolation of high - voltage electrical conductive parts and support. The products can be used in a temperature from -40 ℃ to 40 ℃with an altitude up to 4,000 meters. As for clean, lightly polluted, moderate and serious pollution area, there are different kinds of insulators to choose from. Porcelain Surface is usually brown Glaze or applying white glaze, ash glaze or Fittings of metal surface of hot - dip galvanizing according to the requirement of the customers.
A national advanced electric porcelain assembly product line has been built up through introducing advanced technical and equipment from Japan and Germany. With the need of international electric development, our company has been developing new super voltage and extra high voltage products to meet the customers’ needs.
The company has set up sales management, procurement management, production process and quality control as the main line, assisted with workshop management, storage management, accounting, payment receivable, capacity analysis of equipment management, personnel management, computer aided design making etc. ERP model.
