At present, with the continuous development of kejiping, the flame retardant problem has gone from halogen flame retardant in the past to low halogen and non-halogen flame retardant. Companies in the development and production "of" communication power supply with the antiflaming fire-resistant flexible cable, the cable insulation and sheath using the low smoke zero halogen, high decomposition temperature and good mechanical properties of halogen-free, polymer materials, due to cable contains no halide and metal oxide, in does not produce harmful gases, and a lot of smoke, there is no cause the possibility of "secondary disasters", and it also has good mechanical properties and electrical properties, the operating requirements of cable, completely changed the deficiency of past flame retardant cable.

　　本厂生产的射频电缆的结构是多种多样的，可以根据不同的方式和型式来分类。射频电缆按结构分类（1）同轴射频电缆同轴射频电缆是常用的结构型式。由于其内外导体处于同心位置，电磁能量局限在内外导体之间的介质内传播，因此具有衰减小，屏蔽性能高，使用频带宽及性能稳定等显著优点。

　　6、铠装通信电缆电气特性：电缆符合基本电缆的全部电气要求。7、电缆长度：机械保护型电缆是根据相应基本电缆的标准长度制造。用途实心绝缘非填充型电缆用在交换区域做配线用，主要用于管道敷设，在架空安装时需要用吊线支承。

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. Identification and length marking

The total shielding structure can adopt copper wire and copper band combination shielding, copper wire braid shielding, copper wire braid shielding, copper wire braid shielding, etc. The shielded cable of this structure can resist electromagnetic induction, poor grounding and power line, reduce inductance and prevent the induction electromotive force from being too large.

五极电子管和束射四极管五极电子管是在三极管的基础上，再增加两个栅极，成为具有三个栅极的电子管，g1称为控制栅极，g2称为屏栅极，g3称为抑止栅极。其特殊的结构使得极间电容减小，放大系数增加；束射四极管和五极电子管的不同之处是，它不用抑止栅极，而在阳极和屏栅极之间，装置了一对和阴极相连的聚束板，使其具有较大的功率。复合电子管;将两个或三个独立的电子管合并装在一个管壳内，就形成了复合管电子射线示波管，广泛应用在电子示波仪中作为显示电学量变化的波形，分：电子枪、偏转板、荧光屏，控制电子流运动轨迹的是电场；显像管：电子枪、偏转线圈、高压极、荧光屏，控制电子流运动轨迹的是电场和磁场。

　　铁路信号电缆使用特性：（1）电缆的使用环境温度为-40℃~+60℃（2）电缆导体长期工作温度应不超过+70℃。（3）电缆敷设环境温度：聚氯乙烯外护套电缆应不低于0℃;聚乙烯外护套电缆应不低于-20℃。（4）电缆的允许弯曲半径：非铠装电缆应不小于电缆外径的10倍；铠装电缆应不小于电缆外径的15倍。
