About Dry Type Distribution Transformer
Reliable Insulation and Safety
The transformer employs F/H class insulation and self-extinguishing, non-flammable epoxy resin, enhancing safety by resisting fire and heat. Dielectric strength up to 55 kV and strict adherence to IS and IEC standards ensure dependable operation, even in demanding conditions. This product is meticulously crafted for durability and long-term stability in power distribution applications.
Flexible Design for Various Applications
Manufactured in multiple ratings from 100 kVA to 2500 kVA, this transformer supports custom output configurations, various winding types (toroidal and layer winding), and optional tap changers. Its versatility suits numerous environmentsfrom commercial buildings to industrial facilitiesaddressing a broad scope of electrical distribution challenges. The transformers are available with copper or aluminum windings, matching diverse project specifications.
Efficient Operation and Low Maintenance
Engineered for energy efficiency (approximately 98%) and low noise (below 60 dB), the transformer promises silent and cost-effective operation. With a cooling system supporting both air natural (AN) and air forced (AF) modes, it remains reliable even under heavy loads. Minimal maintenance is required due to robust VPI winding and stringent manufacturing standards.
FAQs of Dry Type Distribution Transformer:
Q: How is the dry type distribution transformer installed and maintained?
A: Installation requires placement in a well-ventilated indoor or outdoor area, following local electrical codes. The robust IP23/IP31/IP41 enclosures minimize environmental impact. Routine maintenance is simpleprimarily visual inspection and cleaning, as the vacuum pressure impregnated windings and solid insulation limit wear. No oil checks or refills are necessary.Q: What are the main advantages of using an insulation class F/H dry type transformer?
A: Insulation class F/H provides enhanced thermal endurance and fire safety. The self-extinguishing, non-flammable epoxy resin reduces fire risk, making it ideal for locations with stringent safety requirements, such as commercial complexes, hospitals, or data centers.Q: When should a tap changer be chosen for use with this transformer?
A: A tap changer is recommended when voltage regulation flexibility is needed. Off-circuit tap links allow adjustment during maintenance shutdowns, while the optional on-load tap changer enables voltage control during operation without interrupting the supply. Choose according to application requirements for voltage consistency.Q: Where can this transformer be used effectively?
A: This transformer suits a wide range of applications, including factories, commercial buildings, institutions, and public infrastructure projects. Its enclosure options and fire-safe design ensure suitability for both indoor and outdoor installations, meeting the demands of diverse electrical distribution systems.Q: What materials and winding techniques are used in construction?
A: The transformer utilizes high-conductivity copper or aluminum windings, shaped using toroidal or layer winding structures. The windings are vacuum pressure impregnated (VPI), offering superior moisture protection and mechanical strength. An epoxy resin coating further enhances durability and electrical insulation.Q: How does the transformer ensure energy efficiency and low noise levels?
A: Precision engineering enables impressive efficiency (about 98%). The optimized core design and winding configuration reduce load losses, while careful mechanical construction and insulation techniques limit noise emission to below 60 dB, supporting quiet operation in sensitive environments.
