Purpose: the self-supporting non-filled cable is suitable for the urban and township telecommunication lines of local telecommunication network, and also for the special network lines connecting to the public network. It is economical and practical to use the same outer protective layer for hoisting line and cable. The mechanical and electrical properties of the cable remain unchanged under conditions of 30~C - 60~C. Structure: wire: annealed bare copper wire, copper wire diameter is 0. 4, 0. 50, 0. 60, 0. 70, 0. 80, 0. 90 mm. Insulating material: high density polyethylene or ethylene-propylene copolymer. The color of the insulated wire is in accordance with the full chromatographic standard. Pair of insulated wires: two different colored insulated wires are twisted in pairs according to different pitch and are identified by a specified chromatographic combination. Core structure: with 25 pairs as the basic unit, more than 25 pairs of cables are assembled according to the unit, each unit is wired with the unit of specified chromatogram to identify different units. 100 pairs or more of cables plus 1% of the reserve pair. Core tape: wrap with a polygrease film tape. Shielding: the two sides are overlapped with or without corrugated metal strip, beyond the cable core of the longitudinal capsule. The plastic film coated on the surface of the shielding belt and the bonding sheath of the protective layer: black low density polyethylene. Hoisting line: the hoisting line is 7 strands of galvanized steel strand, nominal outside diameter is 6. 3 and 4 mm. The tensile strength of two types of 75mm is not less than 3000kg and 1800kg respectively. The suspension wire is coated with thermoplastic paint to prevent the steel wire from corrosion.

三角形接法和星形接法，其实都不难。星形接法，其实就是把电动机的三个绕组，其中的一端头或者尾连接在一块，另一端尾或者头分别接三相电源。而三角形接法，就是把电动机的三个绕组依次连接以后，再接三相电源。比如，电动机的三个绕组头分别是1，2，3；尾分别是4，5，6那么，三角形接法就是1连接4，2连接6，3连接5。本文中大的问题是电动机出线已经没有标识了，那么，第一步要做的就是，区分三个绕组的“头和尾”。利用万用表毫安挡测量，原理是剩磁发电原理:将电动机的三绕组中每一绕组的一根引出线接在一起默认是头，并做好标识，余下三根引出线（每个绕组一根）也接在一起。
