對于防爆電機散嵌繞組，則要另加相間絕緣。其層數、材質(zhì)與槽部相當即可。若槽部采用兩層，相間宜仍采用一層時(shí)，可按下列辦法處理。當槽部絕緣用一層0.2-0.25mm的NMN，加一層0.05-0.1mm的薄膜，若薄膜主要的用途是在槽口處“挽袖”，以加強槽口處絕緣時(shí)，相間只用一層0.2-0.25mm的NMN即可。當槽部用兩層0.2-0.25mmNMN時(shí)，相間可以用一層0.3mm的NMN。相間絕緣的尺寸，要按繞組端部形狀裁剪。裁剪時(shí)，其外緣應大出每極相組線(xiàn)圈端部5mm左右；同時(shí)，還要與防爆電機層間絕緣搭接10mm左右(圖\文www.lfsvw.com/)。

Random winding for explosion-proof motor, to plus a phase insulation. The number of layers, material and the groove can be quite. If the slot is made of two layers of alternating, should still use one layer at a time, according to the following approach. When the grooves of the insulating layer of 0.2-0.25mm NMN, add a layer of a thin film of 0.05-0.1mm, if the film main use is in the notch " armbands ", to strengthen the slot insulation, and only a layer of 0.2-0.25mm NMN. When the slot with a two layer of 0.2-0.25mmNMN, and can use a layer of 0.3mm NMN. Interphase insulating size, according to the winding end shape cutting. When cutting, the outer edge of each pole phase group should be a coil end is about 5mm; at the same time, but also with the explosion-proof electrical insulation between layers lapped around 10mm.
