Description
400 kVA 10 kV Oil-immersed Transformer
I. Core Content
400 kVA 10 kV Oil-immersed Transformer, mainly for large-capacity heavy-load power supply, suitable for large industrial parks, centralized power distribution hubs and other scenarios. It can be networked with the same specification Oil-immersed Transformer (oil-immersed transformer) and combined with Electric Power Converter (electric power converter) to optimize power transmission and meet the centralized power supply requirements of large-scale scenarios, while balancing stability and economy.
II. Product Features
Strong overload capacity: The 400 kVA capacity can stably meet the high-load requirements of large industrial scenarios. It has outstanding overload capacity. Compared to ordinary oil-immersed equipment, it runs more stably and is less likely to experience downtime.
Excellent sealing protection: Adopting a high-strength sealing structure, it is dustproof, moisture-proof, and corrosion-resistant, suitable for outdoor and complex industrial environments. No frequent maintenance is required, and the long-term usage cost is reduced.
III. Common Questions
Q: Can this transformer meet the continuous power supply requirements of large factories?
A: Absolutely, the 400 kVA capacity can stably meet the centralized power supply of large factories. There is no pressure for long-term full-load operation, and there is no concern about overload issues.
Q: Is it necessary to renovate the existing Power Distribution Equipment for connection?
A: No renovation is required. It can be directly connected to Box Type Substation (box-type Transformer Station), High And Low Voltage Switchgear (high and low voltage switchgear), and is compatible with the existing power distribution system.
Q: How to determine if the insulating oil is normal during daily use?
A: Observe the oil color. Clear and without turbidity or odor indicates normal. No professional testing is required. Simple observation can determine it.
