Reliable Surge Protection Technology

The 9KV 5KA Polymer Surge Arrester employs advanced MOV technology and a durable silicone rubber housing to provide efficient surge suppression for power systems. This ensures minimal leakage current and reduces the risk of equipment failure due to voltage spikes, promoting uninterrupted power distribution.

Weatherproof and Durable Construction

With a smooth, matte-finished IP65 case, the arrester is built to withstand harsh weather, high humidity (up to 95%), and chemical exposure. Hot dip galvanized steel end fittings enhance mechanical resilience, while its lightweight build and corrosion-resistant materials simplify installation and long-term outdoor use.

Certified Safety and Performance

Type tested in compliance with IS/IEC standards, this arrester guarantees reliable performance even in seismic and chemically aggressive environments. Its quick response time (<25 ns) and low energy consumption make it a high-efficiency solution for safeguarding transmission lines and distribution equipment.

FAQs of 9KV 5KA Polymer Surge Arrester:

Q: How does the 9KV 5KA Polymer Surge Arrester protect electrical systems?

A: This surge arrester safeguards electrical distribution and transmission lines by diverting excessive transient voltages caused by lightning or switching surges directly to earth, thanks to its efficient MOV (Metal Oxide Varistor) core. It rapidly responds in less than 25 nanoseconds to prevent damage to connected equipment.

Q: What installation conditions are recommended for optimal arrester performance?

A: For best results, the arrester should be installed in a dry, well-ventilated, and outdoor environment. It is compatible with stud mount, bolt, or stud terminal connections and functions efficiently in both horizontal and vertical orientations. Ensure it is mounted securely and avoid exposure to conditions outside its -40C to +60C operating range.

Q: When should this polymer surge arrester be used in a power network?

A: Install this surge arrester on single-phase electrical power distribution or transmission lines, especially where protection against high-voltage surges from lightning or switching is crucial. Its suitable for new installations or for upgrading the safety of existing power infrastructure.

Q: Where can the arrester be used considering its design and certifications?

A: The arrester is suitable for outdoor applications in power substations, distribution poles, or transmission towers. Its IP65 weatherproof rating and tested compliance with IS/IEC standards make it ideal for use in chemically aggressive and seismically active regions.

Q: What are the long-term benefits of using this surge arrester?

A: With its 30-year design life, low maintenance needs, and high resistance to weather, chemicals, and UV exposure, this arrester delivers reliable protection, minimizes power interruptions, and extends equipment lifespan. Its robust efficiency (>98%) and lightweight design add to operational convenience.

Q: How does this arrester ensure safety during extreme environmental events?

A: The arrester is engineered with high seismic resistance and robust hot dip galvanized steel fittings, maintaining performance even during earthquakes. Its housing materials and tight sealing (IP65) protect internal components from moisture, dust, and chemical agents, ensuring operational integrity in extreme weather.
