Descriptions:
To ensure mechanical strength and heat stability we adopt high strength ceramic formula contenting higher aluminium oxide. As per drawing and standard requirement,all post insulator will conduct visual dimension ,geometric tolerance ,ultrasonic test and four-way bending test one by one.
Specifications:
1. Glaze: Light Gray
2. Creepage distance: 940mm
3. Impulse withstand voltage: 250kV
Impulse flashover voltage: 280kV
4. Wet power frequency withstand voltage: 100kV
5. Cantilever strength: 8.9kN Torsion strength: 1.4kN.m
Compression strength: 66.7KN Tension strength: 35.6KN
6. Standard: ANSI C29.9 C29.1
Features:
1. Our insulators have externally attached caps and bases. A highly engineered cementing system transfers the load uniformly from the hardware into the porcelain body.
2. Each insulator body is made from the highest quality clay raw materials that have been processed to be fully vitrified porcelain. The body is glazed to add strength to improve surface appearance, and enhance clean-ability.
3. Either chocolate brown or Munsell gray glaze is available. caps and flanges are ferrous, hot dip galvanized. thread holes are proper tapped.
Competitive advantages:
Reasonable insulation structure high reliability of inter-turn insulation.
Stainless steel flange low magnetic inductivity high resistivity.
Convenient transportation and flexible installation.
Low loss
Low temperature rise
High mechanical strength, strong weather ability.
Outstanding crack resistance
Low thermal expansion coefficient
