但是在电缆燃烧时会释放大量的浓烟和卤酸气体,卤酸气体对周围的电气设备有腐蚀性危害需要带上防毒面具才能接近现场进行灭火。电缆燃烧时给周围电气设备以及救援人员造成危害,不利于灭火救援工作,从而导致严重的“二次危害”。
本厂专业生产电力电缆,YJV,YJVR,RVV质量保证不亏方,外护套质量要求高电力电缆的使用至今已有百余年历史。1879年,美国发明家T.A.在铜棒上包绕黄麻并将其穿入铁管内,然后填充沥青混合物制成电缆。

耐火电缆产品说明产品特点及用途:本产品具有较高的耐火性能,经受火焰直接燃烧下,在一定的时间内不发生短路和短路故障,因此,在火灾发生时,有利于减少损失,低烟无卤型电缆属于环保电缆,尤其适用于对消防要求较高的电力、大型建筑、铁路、船舶等行业产品执行标准Q/HHTZH009.2耐火特性符合GB12666.。

主要技术参数:环境温度:-40℃~+65℃大气压力:70~106KPa相对温度:≤95%任意两端及任一端子与接地之间的绝缘电阻>5×104ΜΩ。任意两端及任一端子与接地之间在接通1000V交流时,1min应无击穿或飞弧现象。
ˎ̥9841型通讯电缆STP-120:在低速、短距离、无干扰的场合可以采用普通的双绞线,反之,在高速、长线传输时,则必须采用阻抗匹配(一般为120Ω)的RS485专用电缆(STP-120Ω(for RS485 & CAN) one pair 18 AWG),而在干扰恶劣的环境下还应采用铠装型双绞屏蔽。
8h工作制是接触器的基本工作制,约定发热电流参数就是按8h工作制确定的;不间断工作制较8h工作制严酷得多,接触器的触头容易出现氧化而线圈容易出现过热。在不间断工作制下,接触器需要降容使用;断续周期工作制的负载率则分别为标准值的15%、25%、40%和60%;短时工作制下触头的通电时间标准值分别为10min、30min、60min和90min等四种。使用类别接触器有四种标准使用类别,分别是AC-AC-AC-3和AC-4。

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 0. 32, 0. 40, 0. 50, 0. 60, 0. 70, 0. 80, 0. 90 (mm). Insulating material: high density polypropylene or polypropylene, colour of the insulated wire as indicated by full chromatograph. Pair of insulated wires: twist two different colored insulated wires into pairs at different pitch and use the specified chromatographic combination to identify pairs. 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 of cables with more than one pair of cables plus 1% of the reserve pair, but not more than 6 pairs. The gap in the core is filled with oil paste. Core tape: wrap with a polygrease film tape. Shielding: metal strip with or without striping, which is longitudinal wrapped outside the core of the cable. Sheath: black low density polymer. Double sheathed cables can also be provided. Identification and marking: cable outer surface sexual identification mark, mark at no more than alternate 1 m intervals, tag contents are: the diameter of wire, line number, cable type, factory name and year of manufacture, marking at no more than alternate 1 m intervals to mark on the surface, but with the tag stagger. Other structures: according to the needs of users, we can provide armored cables HYAT53, HYAT55 and high frequency isolation cables YATG with strengthened mechanical protection layer.
