Product Details

Product overview
ArTu low-voltage switchgear is a new type of low-voltage fixed partition plug-in switchgear developed by cooperating with Swiss ABB Electric (China) Investment Co., Ltd. and introducing its technology. On the basis of widely absorbing the advantages of similar products at home and abroad, this device is suitable for systems with AC 50Hz and rated working voltage 690V and below, which can fully meet the application requirements of various types of markets, as a variety of power generation, transmission, distribution, power conversion and power consumption control equipment, can be widely used in enterprises, buildings, hotels, municipal construction and other low-voltage power distribution system.
The switchgear is fully in line with national standards GB7251, international standards lEC60439-1.
 
Product Features
ArTu low-voltage switchgear is a new type of integrated power distribution system, which can be applied to the level of various capacity levels with a maximum rated current of 4000A. It can adopt either fixed installation design or plug-in design.
According to the characteristics of ABB Megamax F, Emax, Isomax S, Tmax and other circuit breakers and components, it is combined into a functional unit, which has excellent technical performance, safety and reliability, and reduces failures.
Can be composed of protection, operation, conversion and control and other standard unit module structure, can be used for customers to choose and assemble, the number of single cabinet circuit up to 18.
The isolation between regions and the mutual isolation between the incoming and outgoing lines of functional units are adopted to effectively strengthen the safety protection performance. Form 2, Form 3, and up to Form 4 internal isolation forms are available.
K-shaped profiles meet the requirements of various structural forms, protection levels and the use of the environment. The skeleton has a hole with a modulus of 25mm, which can be expanded for various purposes.
High technical performance: the main parameters in the international leading level.
 
Normal use environmental conditions
Ambient air temperature:-5 ℃ ~ 40 ℃, the average temperature within 24h shall not exceed 35 ℃.
Relative humidity: when the maximum temperature is 40 ℃, the relative humidity shall not exceed 50%. When the temperature is lower, a larger relative temperature is allowed, for example, 90% at 20c ℃. However, considering the temperature change, it is possible to accidentally produce condensation.
Pollution level: 3
Indoor installation use. The altitude is not more than 2000 meters.
The equipment is installed in a place without explosion hazard, chemical corrosion and severe vibration.
Overvoltage category: Ⅲ
Beyond the above conditions of use, the user special requirements, can be negotiated with the manufacturer.

The switch cabinet has the functions of overhead incoming and outgoing lines, cable incoming and outgoing lines, bus connection, etc. Mainly suitable for power plants, substations, petrochemical, metallurgical steel rolling, light industry and textile, factories and mining enterprises and residential areas, high-rise buildings and other different places. It mainly includes high-voltage isolating switch and grounding switch, high-voltage load switch, high-voltage automatic coincidence and segmenter, high-voltage operating mechanism, high-voltage explosion-proof distribution device and high-voltage switch cabinet.

Correct Selection of Breaker Breaking Capacity
On the primary system diagram, the selected circuit breaker, indicating the circuit breaker model, rated working voltage and rated working current, must also be selected for the breaking capacity of the circuit breaker. With user drawings, the breaking capacity of the circuit breaker is not selected, which makes it difficult for the manufacturer to carry out engineering design. The breaking capacity selection should be based on the system short-circuit parameters. If the manufacturer does not understand the system short-circuit parameters, it is difficult to make the correct choice. There are also some user drawings, regardless of the system short-circuit parameters, blindly select high-break parameters, resulting in unnecessary waste of funds. The correct choice of breaking capacity is very important, not only to ensure safe operation, but also to consider reducing product costs.
