China SC Series 10kV Dry-type Transformer Factory - High-Quality Resin Cast, Reliable Suppliers
General Features
Flameproof & Safe
Flameproof, explosion resistant, no pollution to environment. Adopting imported epoxy resin and glass fiber compound insulation materials, heat conduction coefficient and flameproof ability is greatly improved. No toxic or harmful gas produced under high heat.
Moisture Resistant
The coils could not absorb moist. The core clamp is coated with special anti-corrosive material. It can work under severe conditions without requiring moist-release-treatment on interval running.
High Impulse Level
Short circuit resistant, high lightning impulse level, ensuring high reliability and stability under electrical stress.
Heat Dissipation
Good heat dissipating due to thin resin coating. Normally adopts natural air cooling (AN). Can be fitted with fan cooling system (AF) to improve short time overload ability.
Low Loss & Maintenance-Free
Low power loss, low noise, good electric saving, economical running, and completely free of maintenance.
Compact & Economical
Small volume, light-weight, small occupied area, low installation costs. No need to build oil release pools, fire proof or fire fighting facilities.
Safety & Cost Efficiency: Without any risk of fire disaster or explosion, it can be installed separately around the loading center, near the electric using point, decreasing wiring costs and saving expensive low voltage costs.

Frequently Asked Questions (FAQ)
What are the main advantages of SC series dry-type transformers?
SC series dry-type transformers are flameproof, explosion-resistant, and environmentally friendly. They offer low power loss, low noise, high short-circuit resistance, and require no maintenance. Their compact design also eliminates the need for oil release pools and fire-fighting facilities.
Where are SC series dry-type transformers typically applied?
They are ideal substitutes for oil transformers and are widely used in high-rise buildings, commercial centers, hospitals, airports, underground railways, tunnels, marine ports, petroleum drilling platforms, and chemical factories.
Can these transformers operate in highly humid environments?
Yes. The coils do not absorb moisture, and the core clamp is coated with a special anti-corrosive material, allowing the transformer to function reliably under severe environmental conditions without requiring frequent moisture-release treatments.
What cooling methods are available for the SC series?
They normally adopt Natural Air Cooling (AN). However, they can be fitted with a Fan Cooling System (AF) to enhance short-time overload capacity and ensure safe operation.
Is it safe to install the transformer directly near the load center?
Yes. Because there is no risk of fire or explosion, these transformers can be installed safely near the electrical load center, which helps decrease wiring costs and saves on expensive low-voltage cabling.
What information is required when placing an inquiry or order?
You should provide the transformer type, rated capacity (kVA), phase/frequency, rated voltage (HV/LV), tapping range, connection symbol, short-circuit impedance, cooling method, degrees of protection (IP rating), and service conditions (altitude/temperature).
