China SC Series 10kV Dry-type Transformer Suppliers - High Reliability and Durable Factory Solutions
General
◆ Flameproof, explosion resistant, no pollution to environment. Adopting imported epoxy resin and glass fiber compound insulation materials, and certain percentage silicon powder in epoxy resin, heat conduction coefficient and flameproof ability is greatly improved than old-type epoxy resin with glass fiber materials. This resin will not produce toxin and harmful gas under high heat.
◆ The coils could not absorb moist. The core clamp is coated with special anti-corrosive material. It can work under severe conditions. It is not necessary to do a moist-release-treatment on interval running.
◆ Short circuit resistant, high lightning impulse level.
◆ Good heat dissipating because of thin resin coated on outside of the coils, and normally adopting natural air cooling (AN). Any protection level transformer could be fitted with fan cooling system (AF) to improve short time overload ability and ensure safety running.
◆ Low power loss, low noise, good electric saving, economical running, and free of maintenance.
◆ Small volume, light-weight, small occupied area, low installation costs, and it is not necessary to build oil release pool, fire proof and fire fighting facilities, and ready power resources, etc.
8. Without any risk of fire disaster, explosion, it could also be installed separately around loading center, near electric using point, so to decrease wiring costs and save expensive low voltage costs.

Frequently Asked Questions (FAQ)
What are the primary safety features of the SC series dry-type transformer?
The SC series dry-type transformer is flameproof, explosion-resistant, and environmentally friendly. It utilizes imported epoxy resin and glass fiber compound insulation, which prevents the production of toxins or harmful gases even under high heat.
Can these transformers operate in high-moisture or harsh environments?
Yes. The coils are designed not to absorb moisture, and the core clamp is coated with a special anti-corrosive material, allowing the transformer to run reliably in severe conditions without requiring interval moisture-release treatments.
What cooling methods are supported by the SC series?
They normally adopt Natural Air cooling (AN). Additionally, any protection level transformer can be configured with a Fan Cooling system (AF) to safely handle short-time overloads.
Where are SC series dry-type transformers typically installed?
They are ideal replacements for oil transformers in high-rise buildings, commercial centers, hospitals, airports, subways, tunnels, chemical plants, ships, drilling platforms, and mines.
How do these transformers help reduce overall installation costs?
Because they present no fire or explosion risks, they can be placed directly near the load center. This eliminates the need for expensive fire-fighting facilities, oil release pools, and long low-voltage wiring runs.
