China Suppliers SCB11 10kV Epoxy Resin Cast Dry-Type Transformer Factory 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.
1
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.
🏢
Ideal for High-Demand Environments: This outstanding safety performance makes the transformer particularly suitable for key areas with high fire protection requirements and large load demands — including high-rise buildings, airports, subways, metallurgy and petrochemical industries, 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.
3
Vacuum Pressure-Impregnation Technology: 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.
⚡
Ultra-Low Partial Discharge (<5pC): 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
Q
What insulating materials are used in the SGB13-10KV transformer, and are they environmentally friendly?
The SGB13-10KV transformer uses high-quality environmentally friendly insulating materials that are non-toxic, self-extinguishing, flame-retardant, and fire-resistant. They fully comply with international environmental protection and safety standards. In the event of accidental combustion, these materials do not release toxic or harmful gases and produce negligible smoke, making them safe for people and the environment.
Q
What is the partial discharge level of this transformer series, and why does it matter?
The partial discharge level is stably controlled below 5pC. This extremely low level is critical because it significantly reduces insulation aging over time, prolongs the service life of the equipment, and ensures stable, reliable operation throughout the transformer's entire service cycle — even under full-load or intermittent operation conditions.
Q
What manufacturing technology is used to ensure winding insulation quality?
The transformer employs vacuum pressure-impregnation (VPI) technology. The windings undergo strict vacuum pressure-impregnation and curing treatment, ensuring the insulating material fully penetrates every gap in the winding. This process eliminates air bubbles and moisture, improves insulation strength, and enhances the bonding force between the conductor and insulating material to form a solid, durable integral structure.
Q
In which application scenarios is the SGB13-10KV transformer most suitable?
This transformer is especially suitable for environments with high fire protection requirements and large load demands, including high-rise buildings, airports, subways, metallurgical and petrochemical facilities, large shopping malls, and hospitals. Its excellent flame retardancy, low smoke emission, and high reliability make it the ideal choice for public safety-critical infrastructure.
Q
What rated capacities and voltage combinations are available for this transformer?
The transformer is available in rated capacities ranging from 30 KVA to 2500 KVA. High voltage options include 6, 6.3, 6.6, 10, 10.5, and 11 KV, with tap ranges of ±5% or ±2×2.5%. The standard low voltage output is 0.4 KV. Connection group labels include Dyn11 and Yyn0, with short-circuit impedance options of 4.0%, 6.0%, and 8.0% depending on the capacity.
Q
How does the coil compression structure contribute to long-term reliability?
The coil compression uses a pressure block structure that applies uniform pressure to the coil. This ensures the winding remains compact and mechanically stable during long-term operation, preventing insulation degradation caused by coil loosening. As a result, the transformer can maintain consistent performance over its entire service life with minimal maintenance requirements and reduced downtime.
