- Product Overview
The YB囗-12/0,4(F R)-630 prefabricated substation combines high-voltage distribution equipment, transformers, and low-voltage distribution equipment into a compact, integrated power distribution unit. It is suitable for three-phase AC power distribution systems with a rated voltage of 12kV and a rated frequency of 50Hz. It can be used in residential areas, large construction sites, high-rise buildings, and industrial and mining enterprises with capacities of 630kVA or less.
- Product Features
● This product is composed of high-voltage distribution equipment, transformers, low-voltage distribution equipment, a shell, and accessories connected and combined according to a certain rule. It is divided into three functional compartments: high-voltage compartment, transformer compartment, and low-voltage compartment. Each compartment has complete functions, a reasonable structure, and reliable component performance.
● The high-voltage compartment consists of a ring network cabinet to form a primary power supply system. It can be arranged in various power supply modes, such as ring network power supply, terminal power supply, and dual power supply. High-voltage metering components can also be installed to meet the requirements of high-voltage metering.
● Transformers can be selected from S11/13 low-loss oil-immersed transformers, amorphous alloy transformers, or dry-type transformers.
● The low-voltage compartment uses low-voltage components to meet the user's power supply requirements, with various functions such as power distribution, lighting distribution, reactive power compensation, and electricity metering, meeting different user requirements and facilitating user power supply management and improving power supply quality.
● The shell can be made of various materials such as high-quality cold-rolled steel plates, stainless steel plates, and aluminum-zinc coated plates. After anti-corrosion treatment, it can prevent rainwater and small animals from entering, and it has the conditions for long-term outdoor use, ensuring anti-corrosion, waterproof, and dustproof performance, long service life, and beautiful appearance.
