Product advantages

High line operation efficiency, excellent electrical corrosion resistance, light weight, excellent mechanical performance, good pollution flashover resistance, good structural stability, good aging resistance, etc.

Product characteristics

  • Insulator is one of the key components in high voltage transmission line, its performance directly affects the whole the safety operation of the transmission line.
  • The slope ratio of glass insulator is one of the important indexes to measure the product quality, and it is also the quality basis of the current power transmission project bidding.
  • Toughened Glass insulator can be used to cancel the periodic preventive test of the insulator in operation. This is due to every damage to tempered glass causes damage to the insulator, which operators can easily find when patrolling the wire.
  • It is made of toughened glass. Due to the high mechanical strength of the surface layer of glass insulator, cracks are not easy to occur on the surface. The electrical strength of glass remains constant throughout its operation and the aging process is much slower than that of porcelain.
  • When the insulator is damaged, the pieces of glass near the steel cap and iron foot are jammed, and the mechanical strength of the remaining part of the insulator is sufficient to prevent the insulator string from breaking off.
  • Insulator is a special insulation control, which can play an important role in overhead transmission lines.
