Pillars of a solid rod porcelain outdoor insulators
The use of standard: GB 8287.1 GB 12744
-------------------------------------------------- ------------------------------
I. Overview
Pillars of a solid rod porcelain outdoor insulators for power-frequency voltage 10 ~ 220kV outdoor power plants, substations, power distribution equipment and electrical equipment as part of the insulation and live support.
Insulators apply for ambient temperature -40 ~ +40 ℃, altitude not more than 1000m, but the altitude, taking full account of the impact of external insulation, some products can also be used for the following areas of 3000m above sea level.
Products sub-type general and two major types of tolerance, and pollution prevention could be applied to Ⅱ, Ⅲ, Ⅳ grade polluted area.
Pieces of porcelain insulators for the solid structure, ash gray enamel coated cast iron flange, ductile iron flange hot-dip galvanizing. Products are single-column structure with a simple structure, easy operation and maintenance of security and so on.
Second, model description
