防跳線器：防跳線器用于漆包線大幅度改變方向及作適量導向和防止繞線過程中的跳線。其中間由精密陶瓷制作瓷圈，超精拋光達Ra0.2。瓷圈內裝有高速軸承，使漆包線與瓷圈之內的延遲滑動距離小于0.20mm，保護漆膜完好及保證漆包線的跳動在很小的范圍之內，保持了張力的穩定性。

wire jump preventer: applicable for wire jump preventing during winding. the niddle ceramic roller is made by precise polishing and matched with high-speed bearing so that jump during winding can be minimized to ensure the tension stability.
