Superior Performance for High Voltage Applications

These long rod insulators are specifically designed for overhead transmission lines coping with demanding voltage levels and harsh environmental conditions. Their solid core rod construction and advanced coating ensure stable operation, minimal breakdown risk, and long service life even in polluted or coastal areas.

Adapted for Extreme Weather and Pollution

Featuring high arc resistance, robust UV stability, and salt fog withstand capabilities, these insulators are ideal for regions prone to heavy pollution or severe weather. Their durable, glazed or silicone-coated surfaces reduce risks of tracking and erosion, helping maintain grid reliability under adverse conditions.

Flexible Installation and Multiple Material Choices

Choose from porcelain or advanced composite polymers to meet project-specific insulation and mechanical demands. Mounting options include ball & socket or tongue & clevis fittings for efficient attachment to tower cross-arms or poles, ensuring adaptability across various transmission line configurations.

FAQs of Long Rod Insulators:

Q: How should long rod insulators be installed on transmission lines?

A: Install the insulators on tower cross-arms or poles using the specified hardware, ensuring correct alignment and the use of designated tension fittings. This process improves mechanical stability and prevents undue stress on the insulator.

Q: What are the advantages of using composite polymer versus porcelain insulators?

A: Composite polymer insulators are lighter, offer superior resistance to tracking and erosion, and maintain high mechanical strength. Porcelain types provide traditional durability and low thermal conductivity. Both options meet IEC 61109 / IS:5300 standards.

Q: When is it recommended to use long rod insulators with high creepage distances?

A: High creepage distance insulators are recommended for polluted environments or areas prone to heavy salt fog, as they effectively prevent surface leakage currents and flashovers, thereby enhancing operational reliability.

Q: Where can these long rod insulators be used?

A: They are primarily used on high voltage overhead transmission lines handling voltages from 11 kV to 400 kV. The robust design makes them suitable for both urban and rural installations across varying climatic zones.

Q: What process ensures the insulators suitability for harsh outdoor conditions?

A: High-quality materials, advanced glazing or silicone rubber coatings, and precise manufacturing to IEC/IS specifications ensure excellent resistance to UV, tracking, erosion, and salt fogmaking them exceptionally robust for outdoor use.

Q: What are the main benefits of using these insulators for transmission lines?

A: They offer excellent mechanical strength, high electrical insulation, long-term durability, and reliable performance in polluted or coastal environments, ultimately reducing maintenance needs and improving network uptime.
