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.

也可以要一些程序。
**比较全的项目资料。
图纸,工艺,程序。
书的话,一二百块钱。
如果网上下载的pdf文档**了。

如果自己不是很喜欢,PLC也没有买的必要了。
3,如果自己确实比较喜好。
有很多仿三菱,仿西门子200的PLC,指令一样的,要便宜一半的钱。
当然有钱也可以买原装的。
三菱,西门子仿的数据线,淘宝上也有卖的。
一套下来。
花个2000来块钱也可以。
培训机构不推荐。
如果想从事这一行,先从维护做起。

Armoured communication cable armoring cable type: HYA53, HYAT53, HYA23 HYAT23, HYV22, HYA22 (rat, buried) armoring 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 designed and vulnerable to erosion area 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. 5. The marking contents of armored communication cables include: wire diameter, number of wire pairs, cable model, length, manufacturer name and year of manufacture. 6. Armored communication cable electrical characteristics: the cable meets all the electrical requirements of the basic cable. 6. Cable length: mechanically protected cable is made according to the length of the corresponding basic cable

二极管最普遍的功能就是只允许电流由单一方向通过(称为顺向偏压),反向时阻断(称为逆向偏压)。
二极管可以想成电子版的逆止阀。
二极管电路中,整流二极管的应用最为常见。
所谓整流二极管就是专门用于电源电路中将交流电转换成单向脉动直流电的二极管。
二极管符号及含义图一普通二极管,第一个是国内标准的画法;图二双向瞬变抑制二极管;图三分别是光敏或光电二极管,发光二极管;图四为变容二极管;图五是肖特基二极管;图六是恒流二极管;图七是稳压二极管;二极管是一种具有单向导电的二端器件,有电子二极管和晶体二极管之分,电子二极管因为灯丝的热损耗,效率比晶体二极管低,现已很少见到,比较常见和常用的多是晶体二极管。
