FAQs of Double Stack Rotating Isolator:

Q: How is the Double Stack Rotating Isolator installed?

A: This isolator is designed for outdoor use and can be mounted either horizontally or vertically on a pole or structure. Installation involves secure fixing as per IEC 61467 standards, with attention to proper alignment and electrical connections for optimal performance.

Q: What are the key benefits of its double stack rotating mechanism?

A: The double stack rotating mechanism provides enhanced mechanical strength and improved isolating capability, ensuring reliable operation with a minimum of 2000 mechanical operations. This robust design further enhances operator safety and system integrity during maintenance or fault clearing.

Q: When should I use a motorized versus manual operating mechanism?

A: A motorized mechanism is recommended for applications requiring remote operation, higher operational frequency, or increased safety for personnel. Manual operation suffices in locations with easy accessibility and less frequent switching requirements.

Q: Where is the best application for this isolator?

A: This isolator is best used in 33 kV overhead transmission line systems, especially where robust outdoor equipment is necessary. It is ideal for utility substations, distribution networks, and industrial installations requiring reliable line isolation and safety.

Q: What makes the product highly resistant to corrosion?

A: The isolators components are protected with a thick hot dip galvanization as per IS 2629 / ISO 1461, ensuring resistance to weathering, rust, and corrosion. This enables dependable performance with reduced maintenance needs, even in demanding outdoor conditions.

Q: How does the copper alloy contact with silver plating improve performance?

A: Copper alloy contacts with silver plating offer excellent conductivity and resistance to arcing or oxidation, ensuring low contact resistance, durable performance, and proficient current carrying capability up to 630 A.

Q: What is the typical process for maintenance or inspection of this isolator?

A: Routine visual inspections for mechanical wear, cleanliness of contacts, and tightness of mounting hardware are recommended. Periodic checks should also confirm integrity of surface coatings and smooth mechanism operation, ensuring continued safe and reliable service.
