What are the selection considerations of Guangdong busway section?

Since the national standard does not specify the cross-section of the busbar, the same variety of busbars labelled with the same rated current value...

How to buy the best busbar at the lowest price

Many people believe that the price of a busway does not necessarily depend on the quality of the busway.When human beings are faced with huge loads requiring hundreds of thousands of strong currents, it is very important to choose safe and reliable conduction equipment.

Guangdong busbar connector must be checked regularly

Before checking the busbar components, it is necessary to stop the power to check the busbar system, completely cut off all power supply to the busbar components, use a multimeter to measure whether there is voltage in the conductor, and confirm that there is no power supply to the busbar system, so that it can be checked regularly. Prevent high voltage on the operator to cause bodily injury. When the busway is running for a long time, the temperature of the joints is regularly tested every year to rise, and the temperature of the joints does not exceed 40 degrees.

Matters to be noted in the horizontal and vertical installation of Guangdong bus ducts

Buses are increasingly replacing wire and cable in indoor low-voltage transmission trunking projects.It has been promoted in developed countries abroad and in Hong Kong and Macao in China.In Guangzhou, Guangdong Province, China, more than 90 per cent of the trunking to the floors of buildings of more than 12 floors use bus ducts; bus ducts should be used from 630KVA transformers to distribution cabinets.

Limitations of bus ducts in high-rise buildings

Compared with ordinary cables, bus ducts show strong advantages as the main power supply line, but over time, operating practice shows that bus ducts.

What are the structural characteristics of high-voltage bus ducts

Once you know the scope of bus ducts, you can see that the good features of bus ducts prevail, which has a lot to do with its structural features.So, if you want to know more about bus ducts, you have to understand it from the structural features.In today's rapid development of China's economy, the role of bus ducts is often remarkable.In order to make better use of it, Bianshao will introduce you to the structural characteristics of bus ducts.

Introduction to the construction requirements of low-voltage bus ducts, the causes of short circuit

Busway (see What is a busway for a definition of busway?(After installation, if you do not pay attention to routine maintenance (see bus duct prices), bus duct short circuit can occur.What are the common causes of busway short circuits?The following is a brief analysis of the four causes of busway short circuit.

Guangdong low-voltage busbar installation rules, how to care and maintenance

Busbars shall not be lifted and bundled with bare wire rope, stacked or dragged on the ground.No other operations shall be carried out on the enclosure.Multi-point lifting and forklift shovelling shall be used without damaging the busbar.Busbars shall be stacked in dry, clean warehouses not contaminated by corrosive gases.Flexible packing gaskets should be clamped between the upper and lower busbar conduits and properly stored

Guangdong high-voltage busway selection method, how to accept the busway

In the selection, generally take into account the following factors: fire requirements, insulation should be flame retardant, heat resistance, will not release toxic gases at high temperatures, in the structure to prevent the chimney effect, should be given priority to the selection of dense insulated busway, such as the selection of air-insulated type, it should be set up in the line trough shell of each unit of the fire-stopping isolation; for the particularly important places, should be selected fire-resistant type trough to ensure that the emergency power supply fire to maintain the work of the work. For particularly important places, fire-resistant tanks should be used to ensure the maintenance of emergency power supply under fire.

Guangdong bus ducts to detect the details of the failure of the method

Bus duct in the indoor low-voltage power transmission trunking project to replace the wire and cable.Popularised in developed countries abroad and in Hong Kong and Macao, China.For bus ducts say, busbar problems, as employees should be how to check the busbar, busbar inspection requirements are as follows

Five common ways to repair a busbar system

Modern high-rise buildings and large-scale workshops require huge amounts of electrical energy. In the face of such huge loads, it is necessary to choose safe and reliable conductive equipment, and the busbar system is a good choice.Busbar system is a kind of efficient power distribution device, especially suitable for increasingly high-rise buildings and large-scale factories economic and reasonable wiring needs. When the busway has a large deformation due to improper installation, the copper row of the guide rail will be deformed and stress, reaching the limit state, the guide rail will jump out of the wedge groove and fall off; when the copper row of the guide rail is connected loosely, the copper row of the guide rail will be deformed by the heat, and it will also fall out of the wedge groove.

Characteristics and application areas of Guangdong bus ducts

Many large factories are facing the problem that they can't work properly due to insufficient power supply, which will cause great loss to the enterprise.Bus duct power supply system as a new power supply system came into being, then what is the bus duct system?Here is a detailed introduction.
