Frequently Asked Questions

What is the primary application of this 30KV Anchor Insulator String?
It is designed for securing and insulating bare Al/Ac conductors in 30kV overhead transmission lines, specifically featuring horn spark plugs for surge protection.
What materials are used for the metal components?
The components utilize hot-dip galvanized steel, galvanized trunnion yokes, and aluminum alloy for the anchor clamps to ensure high corrosion resistance and durability.
What is the mechanical strength rating of this insulator chain?
The assembly has a rated mechanical breaking force of 70kN, making it suitable for high-tension anchoring requirements.
What conductor sizes are compatible with the straight anchor clamp?
The anchor clamp is designed for bare conductors with cross-sections ranging from 35/6 mm² to 95/15 mm².
How does the horn spark gap function?
The spark gap serves as a protective device to divert overvoltages (like lightning strikes) away from the insulator plates, preventing electrical breakdown and damage.
What are the electrical withstand capabilities?
It is rated for an impulse withstand voltage of 260kV (1.2/50 us wave) and a 50 Hz withstand voltage of 100kV under wet (rain) conditions.
