Glazed process: The surface of the rheostat adopts high-temperature baking glaze process and high-temperature flame retardant coating, which can effectively prevent dust, moisture and high temperature, and achieve natural heat dissipation.
High-quality resistance wire: The rheostat is uniformly wound with high-quality resistance wire, which has the characteristics of high power and strong overload capacity.
High-strength carbon brush: The carbon brush made of high-quality raw materials is friction-resistant, has sufficient power, excellent contact and stable performance.
