Introduction: From the perspective of a busbar trunking system manufacturer, this article examines three commonly used insulating materials in low-voltage switchgear: polyimide film, epoxy resin, and silicone rubber. These insulating materials ensure the safety and stability of low-voltage switchgear and extend the service life of the equipment. As a professional busbar trunking system manufacturer, we are committed to providing customers with high-quality insulating materials and products to guarantee the safe operation of electrical equipment.
First, let’s examine the basic structure of a low-voltage switchgear cabinet. Such cabinets typically consist of an enclosure, circuit breakers, switches, indicator lights, and other components. Insulating materials are used to electrically isolate the power equipment from the enclosure, thereby providing protection. Below, we will introduce three common types of insulating materials one by one.
1. Polyimide Film: Polyimide film is a high-temperature and voltage-surge-resistant insulating material. It exhibits excellent dielectric properties and mechanical strength, enabling it to withstand elevated operating temperatures and voltages. In the manufacture of low-voltage switchgear, polyimide film is commonly used for insulating busbars, insulating washers, and other components, thereby ensuring the safe operation of electrical equipment.
2. Epoxy Resin: Epoxy resin is a widely used insulating material that exhibits excellent heat resistance, moisture resistance, and chemical corrosion resistance. It can maintain stable insulation performance under high-temperature and humid conditions, making it suitable for applications such as insulating coatings and insulating boards in low-voltage switchgear. The use of epoxy resin can extend the service life of low-voltage switchgear and enhance equipment safety.
3. Silicone Rubber: Silicone rubber is a material with excellent insulating properties and high-temperature resistance. It maintains good elasticity and insulation performance even under extreme temperatures and is resistant to aging and cracking. In the manufacture of low-voltage switchgear, silicone rubber is commonly used for components such as insulating pads and sealing rings, effectively isolating electrical equipment from the external environment and ensuring safe operation.
In summary, the manufacturing of low-voltage switchgear involves the selection and application of a variety of insulating materials. Polyimide film, epoxy resin, and silicone rubber are commonly used insulating materials that play a critical role in ensuring the safety and stability of low-voltage switchgear. As a busbar trunking system manufacturer, we consistently prioritize quality and safety, providing our customers with high-quality insulating materials and products.

Zhenjiang Ximenzi Hosts a Knowledge Competition
A total of nine teams from various departments took part in this competition. After nearly an hour of intense rivalry, the first-, second-, and third-place awards, as well as the Gold Medalist Award, were ultimately presented.
Zhenjiang Ximenzi Conducts EHS Professional Knowledge and Internal Trainer Training
On December 12, Zhenjiang Siemens invited a professional instructor from Shanghai Qian’an Environmental Protection Company to deliver EHS (Environment, Health, and Safety) expertise training and internal trainer development sessions. More than 20 participants, including heads and supervisors of the Production Department, equipment administrators, and selected frontline employees, attended the training. The curriculum covered mechanical safety safeguards, hazard identification, and risk assessment, with an introduction to practical tools such as energy control and lockout/tagout procedures. During the session, the instructor enhanced trainees’ understanding of how unsafe behaviors lead to accidents by showing short animated videos on behavioral safety. This training marked the first phase of the company’s EHS program; going forward, Zhenjiang Siemens will implement a comprehensive EHS training plan as scheduled to further elevate the company’s EHS management standards.
