Resin cast bus duct is a common device in power systems. Its outer surface is smooth and the overall structure presents a solid and compact structure. Their overall size and shape are often designed based on specific electrical system needs.
Inside is a busbar system of cables, conductors and support structures, which are firmly held together by resin. The resin casting process ensures uniformity and high adhesion of the material, thereby improving the overall performance of the electrical device. When installed and maintained, resin cast bus ducts generally exhibit good wear resistance and durability.
The functions of resin cast bus duct are as follows:
Insulation Protection: Resin casting provides effective insulation, protecting the busbar from moisture, dust and other external environmental factors, reducing the risk of electrical equipment failure.
Anti-corrosion and moisture-proof: The resin has excellent anti-corrosion and moisture-proof properties, helping to extend the service life of the busway, especially in humid or corrosive environments.
Mechanical Protection: Cast resin creates a strong protective layer that prevents mechanical damage to the busbar duct from external objects, such as impact, crushing or vibration.
Improve the insulation strength: The use of resin improves the insulation strength of the bus duct, helps ensure the normal transmission of current and reduces the risk of insulation breakdown.
Thermal stability: Resin usually has good thermal stability and can maintain stable electrical properties within a certain temperature range, making it suitable for different working environments.
Simplified maintenance: Cast resin tightly wraps the bus duct, reducing the need for maintenance and making the equipment more durable and reliable for long periods of time.
