Technical Specifications

Technical Specifications of 30KV Anchor Insulator String with Horn Spark Plugs

The anchor insulator chain with horn spark gap is composed of:
  • A galvanized trunnion yoke
  • A hot-dip galvanized ball eyelet
  • A hot-dip galvanized adjustable extension
  • Three insulator plates for 30kV each with a ball-joint eye housing cover and a base with ball joint (Hot-dip galvanized malleable cast iron)
  • A straight anchor clamp with conical wedge tightening made of aluminum alloy and hot-dip galvanized steel (For bare Al/Ac conductors 35/6 mm² to 95/15 mm²)
  • A simple cross spark gap
  • A ball-socket, supplied with bent pins
  • Two small, short stirrups
The characteristics of the insulator are:
Impulse withstand voltage (1.2/50 us) 260kV
Withstand voltage at 50 Hz (Rain) 100kV
Mechanical breaking force 70kN
Diameter 175mm
Pitch between plates 110mm
Vanishing line 185mm

Frequently Asked Questions

1. What is the maximum voltage capacity for this insulator string?
The system is designed for 30kV applications, featuring an impulse withstand voltage of 260kV (lightning wave) and a 100kV withstand voltage at 50 Hz in rainy conditions.
2. What are the material specifications for the metal components?
Most metal parts, including the yoke, eyelet, and extension, are made from hot-dip galvanized steel or hot-dip galvanized malleable cast iron to ensure maximum corrosion resistance.
3. What is the mechanical strength rating of this product?
The 30KV Anchor Insulator String is designed with a mechanical breaking force of 70kN, ensuring stability in high-tension environments.
4. Which conductor sizes are compatible with the anchor clamp?
The aluminum alloy straight anchor clamp is designed for bare Al/Ac conductors with cross-sections ranging from 35/6 mm² up to 95/15 mm².
5. Does the set include lightning protection?
Yes, the assembly includes a simple cross spark gap (horn spark plugs) specifically designed to protect the string from lightning-induced surges.
6. What is the pitch and vanishing line of the insulator plates?
The pitch between plates is 110mm and the vanishing line (creepage distance) is 185mm.
