Product 1
Development technology/material/manufacturing process nameShaft Grounding Ring
Innovation HighlightsIf not properly controlled, shaft current in new energy vehicle motors can cause bearing electrical erosion, grease degradation, abnormal noise, and even motor failure.
With a modular, lightweight design, this product integrates highly conductive, wear-resistant carbon fiber with a precision-engineered structure to dissipate shaft current to ground and help reduce bearing damage risk.
Bench testing shows stable dynamic contact resistance below 10Ω and wear-life performance equivalent to over 300,000 km of service. This solution helps improve motor reliability, extend vehicle service life, and reduce after-sales maintenance costs.
Applications New energy vehicle motors, electric drive systems, rail transit, industrial motors, wind power generators, etc.

Product 1
Development technology/material/manufacturing process nameSilicone Rubber Resin Fiberglass Sleeve
Innovation HighlightsHigh-voltage systems in new energy vehicles and aerospace wiring harnesses are exposed to harsh challenges such as high temperatures, short circuits, and fire hazards.
This product is manufactured through a specialized braiding, co-extrusion, and vulcanization process, with silicone rubber as the insulation layer and fiberglass as the reinforcement structure. It delivers excellent electrical insulation, thermal aging resistance, and VW-1 flame-retardant performance.
Compared with conventional sleeving, it offers a higher temperature rating and longer service life. It helps protect circuit safety under extreme operating conditions, improves system reliability, and is designed to meet the requirements of high-end global markets.
Applications circuit insulation protection for new energy vehicles, special vehicles, rail transit, military aerospace, etc.

Product 1
Development technology/material/manufacturing process nameBinding rope,Braided Sleeve
Innovation HighlightsWiring harness bundling in aerospace and rail transit applications must withstand demanding requirements such as high temperatures, vibration, and flame retardancy.
This product is made with a high-performance braided structure of para-aramid 1414 or PPS fibers, providing excellent thermal aging resistance, flame retardancy, high tensile strength, and lightweight performance.
Compared with traditional cable ties, it reduces weight and improves vibration fatigue resistance. It helps prevent harness loosening and abrasion, enhances system-level safety and reliability, and supports long-term operation in extreme environments such as nuclear power and wind power applications, while reducing lifecycle maintenance frequency.
Applications aerospace, automobiles, rail transit, nuclear power, hydropower and power grid engineering
