Product Description
Oil-immersed Power Transformer
Kaibian oil-immersed transformers are widely used in residential communities, commercial complexes, industrial and mining enterprises, power stations, public facilities, and urban/rural power grid upgrading projects. They are suitable for 10kV / 20kV / 35kV distribution and transmission systems with stable performance in various load fluctuation conditions and harsh environments.
Kaibian is a professional manufacturer specializing in high- and low-voltage transmission & distribution equipment and electrical components, and is one of the excellent suppliers of State Grid Corporation of China.
Main Products:Oil-immersed transformers, dry-type transformers, CT/PT transformers,YBW prefabricated substations (European/American style),HV switchgear: KYN28A, KYN61, XGN, HXGN, SHSRM, etc.LV switchgear: MNS, GCS, GCK, GGD, XL series,Vacuum circuit breakers, load break switches, and complete power distribution solutions.
Product Description
Product Advantages
1. High-quality silicon-steel core, low no-load loss & low noise
Using high-grade silicon steel sheets with 45° multi-seam lamination, ensuring high lamination coefficient, reduced no-load loss, and lower operational noise.
2. Fully-sealed corrugated tank — maintenance-free and extended service life
The sealed design keeps transformer oil isolated from air, preventing oxidation and moisture ingress, reducing maintenance and improving service life.
3. Strong short-circuit withstand capability
Reinforced structure and mistake-proofing scheme ensure excellent short-circuit tolerance and consistent product quality.
Product Advantages
4. High overload performance for peak-load scenarios
High-overload models support:
1.5× rated capacity for 6 hours
1.75× for 3 hours
2.0× for 1 hour
1.75× for 3 hours
2.0× for 1 hour
Ideal for rural peak seasons, holiday load surges, etc.
5. Low partial discharge, excellent thermal stability, and safer operation
Ensures low PD, high thermal performance, low noise, and strong overload capabilities.
6. Compact size & appealing appearance
Small footprint and clean design make it suitable for various installation environments.
