Cantilever Porcelain Insulator for Electrified Railway Pin post insulator for pole line Solid-core station post porcelain Line Post porcelain Insulator ceramic insulation

Line post insulator

57-2L series type

OEM production is accepted

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-based line post insulators are often used in applications to avoid the need to install a cross-arm on the pole.

We offer a wide range of porcelain station post insulators. 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 lines, 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.

One-stop factory!

A. Professional Manufacturer of insulators above twenty years experience

B. Certificates: ANSI, IEC, BS, DIN, XIHARI, AS, SA

C. A wide range of low and high voltage insulators

  • Post insulator
  • suspension insulator
  • spool insulator
  • shackle insulator
  • stay insulator
  • pin insulator
  • line post insulator
  • wiring insulator

The products are suitable for electric-railway of complex operation conditions, can effectively  prevent flash accidents and decrease the times of clear and maintenance, because of small  volume, and when in the tunnel is clear products of glass insulator cannot instead of it. Polymer type is also produced.
