High and low voltage distribution (Acceptance code for high and low voltage distribution rooms)

1. High voltage distribution: In a power station or substation, electricity is boosted to a high voltage level through a transformer, usually 110 kV or more. High-voltage transmission lines carry electricity to substations or distribution stations in various regions. Such high-voltage transmission lines usually use towers or buried cables to reduce energy losses and transmission losses.

2. Low voltage distribution: In the substation or distribution site, the high voltage power is reduced by the transformer to the low voltage level suitable for end users. Typically, low-voltage distribution has a voltage of 400 volts (V) or less and is suitable for a variety of locations such as homes, commercial buildings, and industrial facilities. Low-voltage distribution systems usually include equipment such as switchboards, distribution boxes, switches and sockets, and corresponding cables or wires.

The design and operation of high and low voltage distribution systems need to strictly comply with relevant safety standards and regulations to ensure the stable operation of the power system, while ensuring the safety of personnel and equipment.
