Customization of fire-resistant busbar trunking drawings

Main performance characteristics:

Based on its unique design, the fire-resistant bus duct exhibits the following outstanding performance characteristics:

1. High reliability: The primary goal of its design is to ensure uninterrupted power supply under certain conditions. This reliability has been verified through rigorous simulated fire testing.

2. Good fire resistance: This is its most essential characteristic. Its fire resistance duration is usually tested and certified according to international or national standards to ensure effective operation within the nominal time.

3. Mechanical strength and durability: In order to maintain structural integrity in a fire, the outer shell and internal support usually have high mechanical strength, which can withstand certain impacts and vibrations, and to some extent improve the durability of the product in daily use.

4. Relatively convenient installation: Compared with laying a large number of fire-resistant cables, the use of bus duct scheme can achieve modular installation of the main line, reduce on-site joints, and improve installation efficiency and quality controllability.

5. Easy maintenance: Adopting a modular design, daily inspection and maintenance are more intuitive and convenient than checking a large number of scattered cables.

Precautions for selecting fire-resistant busbar trunking:

(1) Certification standard: Check whether the product has passed the relevant national fire protection standard testing, such as GB/T9978 fire resistance test.

(2) Material quality: Focus on the fire resistance performance of the insulation layer and shell, and avoid using products made of inferior materials.

(3) Manufacturer qualification: Choose manufacturers with production experience and technical strength to ensure product reliability.

Difference from ordinary bus duct:

Ordinary bus ducts focus on conductivity efficiency and heat dissipation, while fire-resistant types emphasize safety and durability. Fire resistant products have higher costs, but their reliability in the environment is far superior to ordinary models. When choosing, it is necessary to weigh the actual needs, for example, ordinary type can be used in non hazardous areas, while fire-resistant type should be preferred in safety critical areas.

Maintenance and upkeep:

The daily maintenance of fire-resistant bus ducts is important for extending their service life:

(1) Regularly check if the casing is intact to avoid mechanical damage or corrosion.

(2) Clean up accumulated dust to prevent it from affecting heat dissipation.

(3) Check if the connection parts are loose to ensure stable power transmission.

When selecting and using fire-resistant bus ducts for production, the following aspects should be noted:

1. Clarify fire resistance requirements: Determine the required fire resistance time level based on the nature, height, and fire safety regulations of the building (for example, whether to ensure a power supply time of 120 minutes or 180 minutes). This is not about the longer the time, but about meeting regulatory requirements to avoid unnecessary cost increases.

2. Investigate the manufacturer's qualifications and product certification: Select manufacturers with formal production qualifications and products certified by national process fire testing institutions. Require suppliers to provide detailed testing reports to verify the authenticity of their fire resistance performance.

3. Pay attention to details and craftsmanship: High quality busbar trunking products are finely crafted, with a flat and burr free outer shell, uniform spraying, neat arrangement of internal conductors, and full filling of insulation materials. You can request to view samples or visit the production line.

4. Professional installation is crucial: the installation of bus ducts is diversified and carried out by a professional team. Ensure that the installation environment is dry and clean, the torque of the connecting bolts reaches the specified value, and the insulation resistance of the entire circuit meets the requirements. Improper installation can seriously affect its performance and even pose safety hazards.

5. Regular maintenance and inspection: After being put into use, the appearance of the bus duct should be checked regularly for any damage, and there should be no signs of overheating at the connection points (which can be detected by an infrared thermometer). The surface dust should be cleaned regularly to ensure good heat dissipation.
