Suspension Insulator Components

Insulator components

Our suspension insulators are engineered with high-quality elements:

  • Dielectric: Toughened glass with optimal shape for diverse environmental conditions.
  • Cap: Hot-dip galvanized nodular or ductile malleable cast iron.
  • Pin: Hot-dip galvanized forged steel for maximum durability.
  • Assembly: Assembled using specialized aluminous cement to withstand thermomechanical stress.
  • Locking Device: Stainless steel or phosphor bronze split pin (R-pin or W-pin) for secure coupling.
  • Protection: Optional zinc sleeve (sacrificial anode) available for high-pollution environments.

Frequently Asked Questions

What does the "U210B" model name signify?
"U" refers to a Disc Suspension Insulator, "210" indicates a rated Mechanical Failing Load of 210kN, and "B" stands for the Ball and Socket type connection.
Which international standards do these insulators comply with?
The products are manufactured in accordance with IEC60383-1:1993, GB/T1001.1, and connection structures comply with GB/T4056-2008 (IEC60120:1984) and BS 3288 part III.
What is the standard locking pin used for the U210B?
Unless otherwise specified by the customer, an R-pin is typically used for the U210B model. W-pins are also available upon request.
Are these insulators suitable for polluted environments?
Yes. For heavy pollution areas, we strongly recommend adding a sacrificial zinc sleeve to the pin to protect against corrosion.
What material is used for the insulator cap and pin?
The cap is made of hot-dip galvanized nodular or ductile cast iron, and the pin is made of hot-dip galvanized forged steel to ensure long-term reliability.
What is the creepage distance of the U210B/170?
The U210B/170 insulator has a total creepage distance of 400mm, providing excellent insulation performance.
