The product can be laid on any head drop condition even vertically in any place, that is to say, the cable can be laid without limit on head drop.三、產(chǎn)品執(zhí)行標(biāo)準(zhǔn)Standards7GB/T 額定電壓1 kV(Um= kV)到35 kV(Um= kV)擠包絕緣電力電纜及附件第1部分：額定電壓 1kV(Um= kV)和3 kV(Um= kV)電纜Power cables with extruded insulation and their for rated voltages from 1kV(Um=) up to 35kV(Um=) Part本產(chǎn)品為通常條件下使用的產(chǎn)品，不適用一些特殊條件的場(chǎng)合，如架空、水下、船用、海底、核電站等。阻燃聚氯乙烯絕緣電纜適用于具有阻燃要求的場(chǎng)合。1:Cables for ratedvoltages為了便于選擇電纜，將系統(tǒng)劃分為下列三類：The rated voltage of cable shall be applicable to system operation condition where the cable lain in. According to cable selecting, the system will be described as 3 types as follow:——A類：任一相導(dǎo)體與地或接地導(dǎo)體接觸時(shí)，能在1min內(nèi)與系統(tǒng)隔離。System category C ─They are including all systems besides A and B.注：在系統(tǒng)接地故障不能立即自動(dòng)解除時(shí)，故障期間加在電纜絕緣上過高的電場(chǎng)強(qiáng)度，會(huì)在一定程度上縮短電纜壽命。The remended figure of U0 see the table 1, which are suitalbe for the three systems. 表1 額定電壓U0推薦值Table1 The remended figure of U0系統(tǒng)最高電壓Um/kV The maximum system voltageUm/kV額定電壓/kVRated Voltage/ kVA類、B類System categories A and BC類Systems categories C 導(dǎo)體額定工作溫度 The rated temperature of conductor電纜導(dǎo)體的最高額定工作溫度為70℃。The ambient temperature for laying shall be above 0℃, if not the cable need be preheated. 安裝彎曲半徑 The bend radius安裝時(shí)電纜最小彎曲半徑見表2。The cable may be laid in indoor, outdoor, air and soil. The cable may be immersed in water locally.電纜敷設(shè)方式可以是隧道、管道、電纜溝、橋架、排管，鎧裝電纜允許直埋地下，鋼絲鎧裝電纜允許垂直敷設(shè)。The enviroment of cable laying shall be in good heat dissipation condition. 電纜敷設(shè)時(shí)導(dǎo)體最大允許牽引力和電纜最大允許側(cè)壓力The maxium allowed hauloff force and lateral pressure of cable導(dǎo)體最大允許牽引力計(jì)算方法：he calculating method of the maxium allowed hauloff force——銅導(dǎo)體：F=70S（N/mm2）。式中：F－牽引力，N；lateral pressureS－導(dǎo)體截面，mm2；conductor sectionP－側(cè)壓力，N/m；lateral pressureR－電纜彎曲半徑，m；Bend radius 電纜運(yùn)輸和保管要求The requirements on transportation and storage:電纜盤不允許平放。 Including the extruding inner covering and separating tape.2） 非磁性金屬帶包括不銹鋼帶、鋁帶等，若訂貨時(shí)未注明，采用何種材料由制造方確定。Note：The insulation in the cable specifications are the series code.產(chǎn)品表示方法 Expressed method of product示例：鋁芯聚氯乙烯絕緣鋼帶鎧裝聚氯乙烯護(hù)套電力電纜，3+2芯，標(biāo)稱截面150mm2，表示為：*150+2*70 GB/T Q/12BJ49732002Example: Aluniminum conductor PVC insulated, steel tape armoured and PVC sheathed power cables, rated Voltages , 3+2 cores, Nominal cross area 150mm2, see the following:*150+2*70 GB/T Q/12BJ49732002示例：銅芯聚氯乙烯絕緣鋼帶鎧裝聚氯乙烯護(hù)套電力電纜，2芯，標(biāo)稱截面185mm2， 表示為：*185 GB/ Example: Copper conductor PVC insulated, steel tape armoured and PVC sheathed power cables, rated Voltages , 2 cores, Nominal cross area 185mm2, see the following:*185 GB/銅芯聚氯乙烯絕緣（聚氯乙烯內(nèi)護(hù)套）鋼帶鎧裝聚氯乙烯護(hù)套阻燃C類電力電纜，3芯，標(biāo)稱截面150mm2，表示為：*150 GB/T196662005/GB/ Example: Copper conductor PVC insulated, steel tape armoured and PVC sheathed flameretardant class C power cables, rated Voltages , 3croes, Nominal cross area 150mm2, see the following:*150 GB/T196662005/GB/ 銅芯聚氯乙烯絕緣（聚氯乙烯內(nèi)護(hù)套）鋼帶鎧裝聚氯乙烯護(hù)套耐火電力電纜，3+2芯，標(biāo)稱截面150mm2，表示為：*95+2*50 GB/T196662005/ Q/12BJ49732002 Example: Copper conductor PVCinsulated, steel tape armoured and PVC sheathed flameretardant class C firesafe power cables, rated Voltages , 3+2cores, Nominal cross area 150mm2, see the following:*95+2*50 GB/T196662005/ Q/12BJ49732002六、產(chǎn)品型號(hào)、規(guī)格Types and specifications of products產(chǎn)品型號(hào)Type of product產(chǎn)品常用型號(hào)見表3。 For laying indoors 、 in tunnel, cable trench, or direct in ground,able to bear external mechanicalforces, but unable to bear large pulling force 。For product rated voltage, conductor sectiona and the numbers of cores, please see the table 4.表4 產(chǎn)品規(guī)格Table 4 Specification of prouduct型 號(hào)Type芯數(shù)Number of cores標(biāo)稱截面Nominal cross area(㎜2)VV,VYVV22,VV23VLV,VLYVLV22,VLV23110300VV,VYVV22 VV23VLV,VLYVLV22 VLV2324185VV,VYVV22 VV23VV32 VV33VV42 VV43VLV,VLYVLV22 VLV23VLV32 VLV33VLV42 VLV4331630016300VV,VYVV22 VV23VLV,VLYVLV22 VLV23441854185VV,VYVV22 VV23VLV,VLYVLV22 VLV233+141854185VV,VYVV22 VV23VLV,VLYVLV22 VLV233+4+11030010300以上所有的型號(hào)和產(chǎn)品規(guī)格中，阻燃電纜型號(hào)前加ZRA、ZRB、ZRC、ZRD，耐火電纜電纜型號(hào)前加NH,無鹵低煙阻燃電纜電纜型號(hào)前加WDZC。The insulation layer shall be extruded on the conductor, and it shall be easy to be stripped without damages on insulation, conductor and coating layer.隔離套（有鎧裝電纜）Inner sheath（Armoured cables）采用聚氯乙烯（PVC）或聚乙烯（PE）擠包在纜芯上。Note: A large number of facts show that the single cable with the special structure amour in the AC circuit exists the heating phenomenon, thus causing the reduction of current capacity.
