　　火灾中矿用电缆的主要特性有火灾温度一般在600℃～8000℃，在火灾情况下，导线电缆会很快失去绝缘能力，进而引发短路等次生电气事故，造成更大的损失；导线电缆在规定的允许载流量下有较大的过载能力；短路状态下，导线电缆会在瞬间引起绝缘材料熔化、燃烧，并引燃周围可燃物。



　　说的通俗些铠装电缆也就是地埋的电线电缆，动力线传输电能电缆加上铠装层的目的除了增强抗拉强度、抗压强度等机械保护延长使用寿命外，铠装的有一定的抗外力性能，还可以放一些老鼠撕咬，不至于透过铠装造成电力传输问题，铠装的弯曲半径要大，铠装层可以接地保护电缆计算机铠装电缆、计算机铠装电缆：双屏双绞铠装电缆。

低烟低卤、低烟无卤阻燃电缆特点及用途：本产品适用于交流额定电压450/750V及以下的地铁、高层建筑、商场、剧院、发电站、化学工厂、城市广场及其他公用事业等对电缆阻燃特性要求高的场合。电缆的无卤低烟、低卤低烟特性，当火灾发生时，蔓延速度慢，烟浓度低，可见度高，有害气体释放量小，便于人员撤离。

燃烧气体的腐蚀性小，也避免了对仪器设备的损害，低卤、无卤的特性，使得电缆材料在耐老化和耐紫外线及其它辐照性能大大提高，从而延长电缆的使用寿命。

Precautions for installation of power cables: keep 2m distance when the cable is installed in parallel with the thermal pipe, and 0.5m should be maintained when crossing. The cable shall be installed at a distance of 0.5m in parallel or across other pipelines. When the cable is directly buried and installed, the direct buried depth of 1-35kv cable is less than 0.7m. When 10KV and below cables are installed in parallel, the net distance between them shall not be less than 0.1m and 10-35kv shall not be less than 0.25m. The distance of cross installation is not less than 0.5m. Cable laying temperature lower than 0 ℃, bending radius: multi-core cable or 15 (D + D), a single cable 20 or more (D + D), (D for cable diameter, D) for the conductor diameter. ? 6KV and above cable connector:? When installing the terminal head of the cable, the semiconductor electrical shielding layer must be stripped off. During operation, the insulation shall not be damaged. The shield end should be flat and the graphite layer (carbon particles) should be clean. (2) plastic cable end copper tape screened and armor must be good grounding, the short circuit also follow this principle, oid unbalanced three-phase run ShiGang armoured end produce inductive electromotive force, and even "lighter" and sheath and other accidents. It is required to use my tinplate to braid copper wire for grounding lead. When connecting with the cable copper belt, it should be welded with chromium-iron tin. ? The shield of three-phase copper tape should be connected with ground wire respectively. Note that the shielded ground wire and steel armor ground wire should be separately drawn out and insulated from each other. The position of the welded ground wire should be as low as possible. Basic requirements for cable terminals and intermediate joints: a. good conductor connection; B. The insulation is reliable, and it is recommended to use irradiated cross-linked heat-shrinkable silicone rubber insulation materials; C. good sealing; D. sufficient mechanical strength to meet various operating conditions. The end of the cable must be used to prevent water and other corrosive materials from corroding, in order to prevent the water tree caused by the aging of the insulation layer and breakdown. Crane or forklift should be used for the loading and unloading of cables. It is forbidden to run flat or lay flat. For installation of large cables, cable laying cart should be used to oid external damage or abrasion caused by manual dragging. If the cable cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight from exploding and water entering the end of the cable. ? Note: the installation of wire and cable should be familiar with the performance of wire and cable installation personnel or full-time technical personnel, if there are still unclear matters, ball related technical department or technical department of our factory.



To cable, we choose high electrical insulation materials production, such as special cable 1.8/3 kv frequency conversion motor, with 10 kv crosslinked insulating materials, special cable adopts frequency conversion motor of 6/10 kv, 35 kv crosslinking insulation materials, conductive shielding, insulation shield and insulation adopts the imported materials. In production, we put special emphasis on the purification of raw materials, shielding and insulating material key, control the uniformity of the insulation eccentricity and insulation outside diameter, which can interface effect, cable electrical properties.
