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 re of the basic cable. 6. Cable length: mechanically protected cable is made according to the length of the corresponding basic cable

本产品具有较强的抗电磁干扰、抗雷击及均匀电场，改善供电品质的特性。特别适用具有精密电子装置的场所，如计算机中心、航空航天监控中心、智能大厦等。产品适用于额定电压0．6／lkV及以下的电力线路中作输送电能用。
C51C语言的基本规则是有限的,可把这有限的规则组合与嵌套起来,就实现了多种多样的功能。常量与变量本质是值,不同的变量只是存储结构的不通。表达式终也是一个值,所以可以通用,可以嵌套。指针变量存放的是地址。数组名不是变量,而是地址常量。数组是相同结构的变量的集合。数组指针与数组名可以通用。从本质上来说，没有多维数组的存在。因为c语言允许数组元素可以为任何类型的对象,可以是整型变量,字符型变量,结构体变量,当然也可以是数组。
煤矿用控制电缆允许的弯曲半径：对有铠装或铜带屏蔽结构的电缆应不小于电缆外径的12倍。对有屏蔽层结构的软电缆，应不小于电缆外径的6倍。对无铠装层的电缆应不小于电缆外径的6倍。产品在全国几十个煤业集团及矿山上使用，获得了较高的评价和赞誉。
为保证电缆和电动机的正常工作，在选择电缆截面时，应遵守以下四条原则：（1）电缆正常运行时，其实际温升应不超过绝缘所允许的高温升。（2）按电缆线路工作时的允许电压损失进行选择。（3）电缆截面的选择要满足机械强度的要求。
