HYAT23 armoured communication cable USES: armoured communication cable mechanical protective layer can be appended to the structure of the cable, with the mechanical strength of the cable, antierosion capability, is vulnerable to mechanical and vulnerable to erosion area and design of telephone cable. Any kind of laying can be adopted, which is more suitable for direct buried laying in rock area. Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyurethane or polyurethane sheath. Sheath thickness may depend on the basic cable outer diameter.
The protective sheath is made of flame retardant material with high safety factor. Adopt advanced technology production, make the impedance uniformity of the cable good. The multi-core cable is more convenient in the rack laying. According to the need can produce flame retardant, cold - resistant, heat - resistant and other special requirements.

HB型步进电机的定子有槽,线圈为集中方式,为达到机械绕线的目的,绝缘构造也加以改进。
以图左为例,日本伺服(股份)公司用的槽绝缘插入绕线的定子,绕线如右图所示。
该方式如上左图所示,定子铁心厚度为电机厚度的1/2,用裙状绝缘材料插人槽中,铁心槽侧面全部被树脂覆盖,利用绕线机的梭子牵引线机械绕制,线圈一个端点固定在接线柱上,另一端连接固定后从引出线出口引出。
用此方法,电机定子与引出线部分可分开生产,便于部件标准化。
