Product Description
High voltage DC relay metallized ceramic new energy arc extinguishing cover alumina ceramic parts manufacturer
1. Description:
Electric vehicles (EV) uses traction motors for moving force. These vehicles may be powered through off-vehicle batteries or may contain an electrical battery, fuel cells, or solar panels to convert fuel to electricity. This technology was introduced in the 19th century and for years it has been used to power trains. In modern times, with the increased focus on renewable energy and reducing carbon footprints, electric cars have come to the spotlight.
2. Feature Advantages:
1) High compressive strength.
2) Anti corrosion
3) Abrasion resistance
4) Impact resistance
5) High precision
