As of now, there are still some companies, busbar accessory manufacturers, that in order to continue using cast busway in fire protection wiring, apply fire-resistant boards or fire-resistant cotton to the resin-bonded busway to achieve fire resistance. In fact, this solidified casting resin material melts at around 200 degrees Celsius and directly aids combustion at around 500 degrees Celsius. Therefore, to meet the fire resistance time requirement in the test method for flame-retardant, fireproof, and fire-resistant properties of busbar trunk systems (busway) as specified in GA/T537—2005, Nantong busbar accessories must be wrapped with very thick fire-resistant cotton. However, at the same time, this causes the heat inside the槽 to dissipate slowly, making the fire-resistant busway less than ideal.iOne generation fire-resistant busway, at least theiThe raw materials used in the first-generation fire-resistant busway do not promote combustion at high temperatures.
High-density busbars are associated with power loss, voltage drop affecting equipment, and potential safety hazards. Therefore, strict quality control of high-density busbars is crucial. Currently, most projects only require three-phase four-wire or three-phase five-wire current, with some projects increasing the IP protection level. During design, it's essential to clearly specify important safety technologies on the drawings to prevent difficulties in project settlements due to technical parameters and to reduce potential safety risks. Technical review includes: ① Current specifications ② Protection level IP ③ Short-circuit withstand current ICWKA ④ Standard busbars, fire-resistant smoke蔓延 busbars, or fire-resistant busbars ⑤ Temperature rise ⑥ Conductor current-carrying capacity ⑦ Protection circuit continuity. If all seven technical data meet the requirements, the certified products can generally be used with confidence. Quality control and inspection for production include checking the conductor for resistance rate measurement equipment, the busbar for withstand voltage testing equipment, the busbar for current-carrying capacity and temperature rise testing equipment, and the protection circuit for continuity testing equipment. These devices directly relate to the pass rate of the manufacturer's products upon shipment. Having these testing equipment ensures that the products shipped provide a valid basis. The review and testing of conductors, busbar accessories pricing, and busbar conductor specifications are discounted by 15-20% compared to the electrical manual's 40°C ambient temperature current-carrying capacity. For busbars with poor structural heat dissipation, the discount is even greater. If there are discrepancies in the current-carrying capacity calculation for high-density busbars, it is recommended to conduct temperature rise limit verification tests.
Performance of enclosed busbars
The busbars we use are widely suitable, commonly employed in warehouses, buildings, and many other voltage application scenarios. Dense busbars exhibit the following characteristics during use.
The busbar performs well in use, featuring low resistive efficiency and high current density, making it an excellent choice for dense busbar applications. Additionally, it consumes very little energy during operation, making it a relatively economical busbar from the manufacturer's perspective.
It is very safe to use. The dense busbars are insulated with protective shells, ensuring minimal harm to humans and animals. Additionally, during installation, there are measures for grounding or connecting to neutral, thus preventing any dangerous accidents during use. The installation and maintenance process is quite safe.
