Our valuable clients can avail these Electrical Power Transformer from us at competitive prices.

Key Features:

Provide constant voltage level
Low maintenance
Hassle-free functionality
Trouble-free performance

Advanced Design & Construction

These transformers feature low-loss CRGO M4/M5 cores, super-enamelled copper windings, and a coil structure designed for optimal performance and longevity. The use of mineral oil (IS 335) enhances insulation and cooling, while mounting options support versatile site requirements. Each unit is crafted for minimal losses and exceptional reliability in demanding environments.

Superior Protection & Safety

Safety is paramount, so our units incorporate essential protective devices like Buchholz relays, pressure relief valves, and oil temperature indicators. Enclosures are IP23 or IP33 rated, sheltering critical components from dust and water ingress, while epoxy/PU painting ensures long-term corrosion resistance even in challenging climates.

Compliance & Testing

Manufactured to rigorous national and international standards (IS 1180, IS 2026, IEC 60076), all transformers undergo comprehensive routine, type, and special tests. Key accessories such as conservators, breathers, thermometer pockets, and explosion vents support reliability and ease of maintenance, guaranteeing performance for decades.

FAQ's of Electrical Power Transformer:

Q: What industries and applications are suitable for these power transformers?

A: These transformers are ideal for industrial, utility, commercial, and substation applications. Their robust build and high efficiency make them well-suited for distribution networks, manufacturing operations, and critical infrastructure in both urban and rural areas.

Q: How is the protection of the transformer ensured during operation?

A: Each unit is equipped with a Buchholz relay, pressure relief device, and oil temperature indicator. Their enclosures are rated IP23/IP33 for ingress protection, and all surfaces are painted with epoxy or PU coatings to prevent rust, ensuring long-term durability and safe operation.

Q: When should I opt for pole mounting versus pad mounting?

A: Pole mounting is typically chosen for smaller capacity transformers in distribution networks where space is limited, while pad mounting is preferred for larger units or installations where enhanced accessibility and stability are required, such as substations or industrial facilities.

Q: Where are these transformers manufactured and to which standards do they comply?

A: Manufactured in India, these transformers adhere to IS 1180, IS 2026, and IEC 60076 standards, ensuring global quality benchmarks. Extensive in-house testing guarantees compliance with routine, type, and special requirement tests.

Q: What is the process for routine maintenance and what accessories support this?

A: Routine maintenance includes oil level and temperature monitoring (using temperature indicators and thermometer pockets), maintaining the breather, and inspecting the conservator and pressure relief mechanisms. Accessories like explosion vents further facilitate safe maintenance and longer operational life.

Q: How does the transformer maintain high efficiency and low losses?

A: Efficiency is maximized (up to 99%) using low-loss CRGO steel cores and super-enamelled copper or electrolytic copper windings. No-load and load losses strictly comply with IS 1180/2026 limits, while optimal coil structure and quality mineral oil further reduce energy losses and enhance cooling.

Q: What are the long-term benefits of installing this transformer?

A: With a typical service life of 25 years, these transformers deliver reliable energy distribution, minimal noise (<65 dB(A)), and reduced operational costs due to high efficiency and durable components. Their rust-resistant, robust construction ensures minimal downtime and supports complex power needs over decades.
