introduction of 35kv power transformer
The 35kv power transformer, the use of company specific calculation and verification procedures, the transformer core, coils, active part, leading tanks and other components for a full range of optimized designand verification,to ensure product performance.Superior technology equipment, careful selection of materials, and efficient manufacturing make the transformer small, light weight, low loss, low PD, low noise and other characteristics of superior product quality, energy saving and environmental protection.reliable operation and effectively reduce the product operating costs
35kV power transformers are mainly divided into two types: oil-immersed transformers and dry-type transformers.
Oil-Immersed Transformers
- Type SZ11: Applicable to voltage levels of 35kV and below, it features high insulation performance and reliability, and is commonly used in power transmission and distribution systems.
- Type S9: An early model, which has been gradually replaced by more efficient models such as Type SCB10.
Dry-Type Transformers
- Type SCB10: Suitable for voltage levels of 10kV and below, it has advantages including fire resistance, moisture resistance and maintenance-free operation, and is often used in industrial, medical and new energy fields.
- SG Series: Specifically designed for voltages below 35kV, with a capacity range of 30-2500kVA, it is widely used in power distribution systems and power transmission and transformation links.
