1. Product Overview
The SCB series epoxy resin cast transformer, made ofdry material,is an energy-saving powertransformertransformer, characterized by high efficiency and energy conservation, as well as significant cost savings. It uses epoxy resin vacuum casting technology and foil winding, ensuring a completely oil-free design. It is fire-resistant, explosion-proof, environmentally friendly, and operates stably and reliably.
As the main equipment in medium and low voltage distribution networks, it is widely used in urban power grid upgrades, commercial buildings, industrial parks, public places, and other locations with high requirements for safety, energy conservation, and environmental protection. It can be installed directly at the building's load center and is adaptable to various complex operating conditions.
2. Main product advantages
Safe and fire-resistant, suitable for various installation scenarios.
The oil-free design and fire-resistant epoxy casting make it fire-resistant and self-extinguishing, completely eliminating hidden dangers such as oil leakage, fire, and explosion, and complying with fire safety regulations. It can be installed directly in basements, distribution rooms, and densely populated areas without an additional fire protection zone, saving installation space.
Environmentally friendly and moisture-resistant material for harsh operating conditions.
No odor or emission of toxic gases during operation, no contamination of soil or water. Windings cured by vacuum casting have high moisture resistance, resistance to mold, salt spray, and pollution, and can operate normally at 100% relative humidity. They can be put back into service without pre-drying, making them suitable for humid southern regions and coastal areas exposed to salt spray.
Stable and reliable operation with a long service life.
Windings made by integral curing have high mechanical strength, high resistance to sudden short circuits and shock waves. Partial discharge is extremely low (≤10 pC) with stable insulation, effectively preventing insulation aging.
Low noise level and easy maintenance.
The optimized magnetic circuit design reduces operating noise to 50–60 dB(A), meeting noise standards for residential and office environments. The compact design, small size, and light weight facilitate easy installation. The device requires minimal or no maintenance and is equipped with an intelligent temperature controller for overheat alarm, protection activation, and fan control. Some models support RS485 communication protocol for remote monitoring and operation management.
