沁阳聚氯护套强壮
Low smoke zero halogen type refractory in addition to meet the low smoke zero halogen flame retardant, the performance of the fire test should be passed GB/T19216-2003 under the condition of the flame or the stipulations in the optical cable circuit integrity experiment, at 750 ℃, 90 min, 2 a fuse fusing.
0.85线芯绝缘厚度为0.7绝缘后外径为2.5毫米。4.成缆时把四根线芯排列为红，绿，蓝，白，排流线，排流线要和线芯一起绞合，千万不要纵放，成缆时不要加填充物，缆芯外用铝箔绕包，而后再绕包一层聚酯膜，在外有一层铜丝编织屏蔽（屏蔽铜丝不镀锡）。
The shielding layer can not only restrain the electromagnetic wave from transmitting, but also act as a channel for short-circuit current, which can protect the neutral core. 6/10 kv dedicated cable frequency conversion motor, considering the cables, external force is often in the process of using radial outside the cable shielding layer increased galvanized steel tape armoured layer (between shielding layer and steel tape armoured layer of sleeve).

MHYVR矿用聚乙烯绝缘、阻燃聚氯乙烯护套信号软电缆1-207/0.30。NHB—VV适用范围：固定敷设于室内、隧道内、托架及管道中要求阻燃耐火的场所。电缆导体长期工作温度不超过+70℃，电缆敷设温度不低于0℃，电缆弯曲半径不小于电缆外径的20倍。
使用方法：根据工作现场的实际照明需要,确定灯具的安装位置和方式,然后按灯具到220V电源接点的距离备好相应长度的三芯电缆线(如采用钢管布线则将三芯电缆线引入钢管至灯具安装处)。先卸下接线腔上的固定螺钉,拔出接线盒的接线部分;从包装盒内取出密封圈和接头(带紧定螺钉),依次套入电缆;然后将三芯电缆线的一端分别接入盒内的标识“L”、“N”和接地处,用压线卡压紧电缆后,并用紧固螺钉固定好,然后拧紧接头,压紧密封圈,并从侧面拧紧紧定螺钉。

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

具体区别方法：看网线截面，如果是铜色的话，就是铜丝，如为白色，则是用合金以次充好。合金一般比较脆，容易断，而且导电性远不如铜丝，很容易在工程施工中造成问题。线材一般那建议选择标准的485线，其为屏蔽双绞线，传输线不是像网线那样为单股的铜丝，而是多股铜丝绞在一起形成一根线，从而即使某根小铜丝断掉，也不会影响整个的使用。

矿用电力电缆具有以下列特性：（1）应能长期承受较高、甚至很高、极高的工作电压，电缆应具有非常优良的电气绝缘性能；（2）能传输很大的电流(几百甚至几千安培)，为此电缆应有良好的热老化性（耐热性）和散热性；（3）电缆应有多种结构的护层以保护绝缘层，适应各种不同敷设环境（地下、水中、沟管隧道）的需要；（4。
万幸没有砸到人，但该事故也足以让人冷汗冒一身。就事故本身来说，不合规范处太多：没有正确记录相位顺序，没有通知相关人员整改情况，没有改后试运营，等等等等。但对“限位”的过分相信也是很重要的原因，确实，当时包括塔吊操作人员在内的许多人都说：“塔吊上装有限位啊。”虽然过份依赖“限位”可能会出问题，但话说回来，“限位”毕竟还是很重要的安全保护手段。那我们能不能让这份保护更加坚固呢？笔者思来想去，也只有应付的一个笨方法：加“保护限位”。
符合IEC331规定符合GB12666.6规定燃烧时间750℃火焰温度950℃~1000℃火焰温度75℃~800℃火焰时间3h燃烧时间90min燃烧时间90min冷却时间12h附加电压额定电压附加电压额定电压附加电压 额定电压附加电流3A附加电流 3A附加电。
严格的说，485总线必须要单点可靠接地。单点就是整个485总线上只能是有一个点接地，不能多点接地，因为将其接地是因为要将地线（一般都是屏蔽线作地线）上的电压保持一致，防止共模干扰，如果多点接地适得其反。
