Product Description

1.Overview
SC (B) 11 dry-type power transformer is an efficient, energy-saving, safe and reliable power transmission and distribution equipment, suitable for power supply and distribution systems in various places such as high-rise buildings, commercial centers, and industrial and mining enterprises. It has efficient skills, safety and reliability, environmental protection and low noise, easy installation, and flexible adaptation. By leveraging advantages such as energy conservation, safety, environmental protection, and strong adaptability, we provide efficient and stable solutions for power conversion and distribution in modern power systems, helping users build reliable and green power supply and distribution systems.

2.Product Advantages
Loss and energy efficiency: The no-load loss has decreased by about 12%, making it more energy-efficient and environmentally friendly. Long term operation can save more electricity costs, improve economic efficiency, and meet the current development needs of energy conservation and consumption reduction.
Mechanical and electrical performance: higher mechanical strength, better short-circuit resistance, less likely to be damaged in the face of short-circuit faults, and improved operational reliability; High insulation level and good lightning impulse resistance, which can better protect equipment and reduce the probability of failure under overvoltage conditions such as lightning.
Operation and maintenance: The maintenance free feature is more prominent, with excellent moisture-proof performance. It can operate in a 100% humidity environment without preheating before operation, and intermittent operation does not require dehumidification treatment, reducing operation and maintenance costs and workload.
Volume and noise: Small in size, lightweight, easy to transport and install, can save installation space; Reduced noise level, quieter operation, and reduced noise interference to the surrounding environment.
Heat dissipation and overload: With strong heat dissipation capabilities, it can achieve 150% rated load operation under cold air conditions, ensuring stable power supply during short-term load peaks and improving equipment applicability and flexibility.
