XL-III INTENSIVE COPPER BUSWAY
Xl-III intensive busway system is a new type of busway system developed by zhenjiang Siemens based on the characteristics of the Chinese market and closer to the needs of users. Typical sandwich structure is adopted inside, which is a flexible and reliable new generation power distribution system with high cost performance. The automatic production degree is higher, which can meet the power distribution needs of different user groups.
1. Chimney protection effect: Siemens xl-iii intensive busway adopts the typical "sandwich" structure, and ensures that the whole length of the busway is dense, and there is no void formed inside, no air flow, effectively preventing chimney effect;
2. Heat dissipation mode: the busway relies on the heat conduction of the overall shell for heat dissipation, which determines that the carrying current of the xl-iii intensive busway system will not be affected by the installation location and installation mode;
3. Protection level: the design of the product fully takes into account the system's protection against external solid and liquid, without requiring users to take other measures to improve the protection level during installation. Greatly reduce the unexpected operating environment caused by the bus slot failure rate. When used in indoor environment, we can provide products with protection grade of IP54~IP65. For bus with socket, due to the influence of socket protection ability, the product protection grade is IP54.
LD bus slot system is air - reinforced insulated bus with good heat dissipation performance.
The system is used for high-current transmission and distribution, and is used for connecting low-voltage distribution cabinets with transformers and heavy loads. With wide current range and complete structure series, it can meet the use of various buildings with different rules, and the system design is novel and flexible, providing users with the possibility to choose a variety of schemes.
1. Quick installation
The compact design of the l-d bus system saves a lot of space. The connection between the connector and the bus depends on a single bolt, saving installation cost. At the same time, the system provides various on-site installation methods, users can choose flexibly according to the needs of the site, the site installation only needs to use torque wrench to tighten the single bolt terminals, the company is equipped with special torque wrench when shipping;
2. Reliable and safe system
IP31 bus system with heat dissipation hole cover to improve the heat dissipation performance, so as to provide a larger load flow. The enclosed cover has a protective level up to I, P, 5 and 4, and can be used in any harsh environment. The bus groove body is of high rigidity. The influence of thermal deformation on the system is considered to ensure the reliability of the system. The ground wire and zero wire which are connected first and then broken ensure the personal safety when using electricity;
3. Connection between LD system and transformer
The transformer transmits power to large equipment and low-voltage distribution cabinet through l-d system. The standard connecting terminals of LD system can be directly connected with transformers of various types and specifications. In order to avoid the impact of vibration caused by transformers during operation on the whole system, soft connection can be arranged between the two connecting terminals, and the maximum current can reach 50, 0, 0, A.
4, fire prevention
Fire prevention is very important in high-rise buildings, so L D bus in high-rise buildings should be used in the use of special fire barrier. In the event of a fire hazard, it can prevent smoke, fire and heat from spreading through the busway unit to the adjacent room or floor, and even prevent water from penetrating during the fire fighting. The fire protection time is 1, 20 min.
