China Suppliers Factory SCB11 10kV Epoxy Resin Cast Dry-Type Transformer with Modular Design for Easy Maintenance
Product Features
This series of transformers takes safety and reliability as the core design principles, integrating high-performance insulating materials, sophisticated coil structures and advanced manufacturing processes. It can stably operate in complex and harsh working environments, and is widely trusted in fields with high safety and stability requirements. The following is a detailed elaboration on its excellent safety performance and high reliability:
Good Safety Performance
The transformer adopts high-quality environmentally friendly insulating materials, which are carefully selected and strictly tested to ensure that the content of combustible components is minimized. These insulating materials have multiple safety characteristics such as non-toxicity, self-extinguishing, flame retardancy and fire resistance, fully complying with international environmental protection and safety standards. In the event of accidental open fire combustion, the insulating materials will not release toxic or harmful gases, and the smoke production is almost negligible, effectively avoiding secondary hazards such as air pollution and personnel poisoning caused by smoke and toxic gases.
Wide Application Scenarios
This outstanding safety performance makes the transformer particularly suitable for key areas with high fire protection requirements and large load demands. Typical application scenarios include high-rise buildings, where the dense population and complex pipeline layout put forward strict requirements on fire safety; airports and subways, which are important transportation hubs with large passenger flow and high reliability requirements; metallurgy and petrochemical industries, where the working environment is harsh and flammable and explosive substances are present, requiring equipment to have excellent flame retardancy and explosion-proof performance; as well as large shopping malls, hospitals and other public places with high pedestrian flow and high fire safety standards. In these scenarios, the transformer can effectively reduce fire risks and ensure the safety of personnel and property.
Advanced Manufacturing Process
The core manufacturing process adopts vacuum pressure-impregnation technology. The windings are subjected to strict vacuum pressure-impregnation and curing treatment, which ensures that the insulating material can fully penetrate into every gap of the winding, eliminating air bubbles and moisture in the insulation layer. This not only improves the insulation strength of the winding, but also enhances the bonding force between the conductor and the insulating material, forming a solid integral structure. In addition, the coil compression adopts a pressure block structure, which applies uniform pressure to the coil, ensuring that the winding remains compact and stable during long-term operation, and avoiding insulation degradation caused by coil loosening.
Extremely Low Partial Discharge
Thanks to the above structural design and manufacturing process, the transformer has an extremely low partial discharge level (stably controlled below 5pC), which can effectively reduce insulation aging caused by partial discharge and prolong the service life of the equipment. During the entire service cycle, the transformer has no risks of cracking, insulation degradation or other common faults, and can maintain stable and reliable operation even under long-term full-load or intermittent operation conditions, reducing the frequency of maintenance and downtime and ensuring the continuous and stable operation of the power supply system.

Frequently Asked Questions
What makes this transformer series safe for fire-sensitive areas?
These transformers utilize high-quality, eco-friendly insulating materials that are non-toxic, self-extinguishing, flame-retardant, and fire-resistant. In the event of an accidental fire, they release no toxic gases and virtually zero smoke, preventing secondary hazards.
Where are these transformers typically installed?
They are widely used in high-load and strictly regulated public spaces, transportation hubs, and industrial zones. Key applications include high-rise buildings, airports, subways, metallurgical and petrochemical plants, shopping malls, and hospitals.
What is vacuum pressure-impregnation (VPI) technology?
VPI is an advanced manufacturing technology where the transformer windings undergo strict vacuum pressure-impregnation and curing. This process completely eliminates air bubbles and moisture within the insulation layer, resulting in superior insulation strength and a solid structural bond.
How does the coil compression design prevent insulation degradation?
The transformer features a pressure block structure that applies uniform force to the coil. This design guarantees the winding remains tight and stable throughout long-term operations, eliminating the risk of insulation degradation caused by coil loosening.
What is the partial discharge level of these transformers?
The partial discharge level is stably controlled below 5pC. This exceptionally low discharge level minimizes insulation aging, significantly extending the operational lifespan of the unit.
Can these transformers operate under continuous full load?
Yes, they are engineered to maintain stable and reliable operation even under long-term full-load or intermittent operation conditions without the risk of cracking or insulation faults, thereby reducing maintenance downtime.
