(Summary description)In many large buildings or important buildings, in addition to normal power supply and distribution, diesel generators are also available as emergency power sources. In normal times, the electricity used by buildings is supplied by the internal power grid through the internal substation. Once the power supply line has a problem or a fire occurs inside the building to cause the mains to trip, the diesel generator set is required to generate electricity for temporary power supply. Ensure that important work does not stop working, or that evacuation lighting indicates that the staff is evacuated. The electricity generated by the diesel generator needs to pass through some of the low-voltage power distribution cabinets of the substation,

Information
In many large buildings or important buildings, in addition to normal power supply and distribution, diesel generators are also available as emergency power sources. In normal times, the electricity used by buildings is supplied by the internal power grid through the internal substation. Once the power supply line has a problem or a fire occurs inside the building to cause the mains to trip, the diesel generator set is required to generate electricity for temporary power supply. Ensure that important work does not stop working, or that evacuation lighting indicates that the staff is evacuated. The electricity generated by the diesel generator needs to pass through some of the low-voltage power distribution cabinets of the substation, and is fed through the low-voltage power distribution cabinet to the power equipment that needs the emergency power supply> power supply. The low-voltage power distribution cabinet of the diesel generator and the substation is a power supply system that is connected by a fire-resistant cable or a fire-resistant closed busway.
 
Due to the fire-resistant cable or the fire-resistant enclosed busway, the busbar acts as a transmission line in the event of a fire or other disaster, in addition to the emergency power supply line when the power grid or line is in trouble. Therefore, fire-resistant cables or refractory enclosed busway slots must be able to guarantee normal power transmission at high temperatures. When the ambient temperature reaches 700 °C or above, the power supply can be operated for more than 1.5 hours without causing a short circuit between the wires due to an increase in the internal temperature.
 
The enclosed busway is composed of a current-carrying conductor, a casing and a rim material. The busbar casing should be made of high-quality cold-rolled steel plate with sufficient mechanical strength and protection class IP55. The current-carrying conductor shall be specially treated with the contact surface of the electrical copper material and the conductor contact in accordance with GB5585.1-5585.3, so that the contact of the joint is reliable, the heat is low, and the use is safe and reliable. The materials should have good performance, anti-aging, non-toxic, low-smoke and other performance indicators.
