We offers a wide range of porcelain station post insulators. For
decades, these products have demonstrated reliable performance in
various types of applications all over the world.
Porcelain insulators are the traditional choice for distribution
and transmission line, busbar and apparatus insulation.
Manufactured from high-quality non-porous electrical porcelain, they provide long life and
cost-effective solutions for a majority of applications.
Features:
1. High strength
2. Competitive price and prompt delivery
3. High voltage application
4. Material: Porcelain
5. ANSI Approve
Applications:
Line post insulators are designed to provide rigid support of conducting cable while offering the maximum resistance to damage from electrical or mechanical events. Horizontal and gain-base line post insulators are often used in applications to avoid the need to install a cross-arm on the pole.
Competitive advantages:
Reasonable insulation structure high reliability of interturn insulation.
Stainless steel flange low magnetic inductivity high resistivity.Small volume light weight.
Convenient transportation and flexible installation.
Low OSS.Low temperature rise.High mechanical strength, strong weather ability.
Outstanding crack resistance.
Low thermal expansion coefficient.
