1kv)Silane XLPE Insulated Power Cable

SILANE XLPE INSULATED POWER CABLE

硅烷交联聚乙烯绝缘电力电缆

一、 Product standard
Enterprise standard:equivalent to GB12706-2002and IEC502-1983
二、 Usage
This product is suitable for use in rated AC voltage （U0/U）0.6/1KV and 1.8/3-8.7/10KV system transmitting and distributing circuit.
三、 Property for Use
1. It is far better than all property targets of PVC insulated power cable and has overcome the short comings of physical and chemical cross- linkage,and completely reaches of surpasses GB and IEC technical property value.
2.The allowed max.cable conductor work temperature is 90℃;urgent excess work temperature is130℃ for short circuit（5s），max.conductor temperature is 250℃.
3.The environmental temperature for laying cable should be not less than 0℃.If laying under0℃，the cable should be preheated.
4.The cable bend radius for single core should be not less than 16 times of overall cable diametet；for multi-core cable，not less than 12 times of overall cable diameter.
5.The current-carrying capacity is large and not limited by drop during laying.
四、Type,Name and scope of Application Table1

Note:We can also design and produce waerproof,fire-resistant series and low smoke，non-halogen and other special type products according to clients’special requirements and technical agreemen.Combustion-retardant and fire-resistant series will be in troduced in detail later. Because“42”“43”are actually rarely used，therefore they are omitted here.
五、 Specifications
For cable specifications，see Table 2.

Note:
（1） The single core armored cable in the list are only suitable for use for DC circuit. If used for AC circuit，non-magnetic material or armored by reducing magnetic loss structure must be used.
（2） 3 2、3 1、4 1cores neutral wire and cross-sestion protection wire are the same,for specifications，refer to all-plastic power cable.

七、Technical Properties
1.   Conductor:generally uses similar or not similar diameter twisted round single wire.This sample book adopts the former technology.
（1） Conductor for 1.8/3KV and below cable：
           a. Single core cable core is round or extruded round，cross-section of multi-core cable core of 35mm2 and below is round,50mm2 and below is fan-shaped or semicircular.
           b. （3 1），（3 2），（4 1）neutral wire and protection core is round or extruded shape, among them5-core power cable may adopt 4 cores plus 1 core twisted to 4-core cable core，or a corrugated shape or five cores extruded into fanshape or 5th core into extruded round shape and other structures.
（2）   Conductor for 3.6/6-8.7/10KV cable:
         a.Adopts highly extruded round shape，wiih extrusion co-efficient(η)not less than 0．87，0．88，0．89，0．90 and 0．91
           according to different cross-sections．
           b.Under special situations，6KV conductor can also be fan-shaped．
(3) Conductor structure adopts min．single wires reaching the standard in Table 3．                               Table 3

(4) Conductor DC resistance reach standards in Table 3
         2．Insulation and Sheath
         2．1、Insulation
         Various voltage grade nominal insulation thickness reach the standard in Table 4．               Table 4

2.2、 Screen．
Screen with various kinds of requirements should reach standards in Table 4．
3． For reference，overall diameter and weight of cable，see Tables 5 - 9．
(1)    Because this content is too long and very tedious for writing，therefore the reference data in Tables 5 - 9 are the most com-
    monly used and universal types and specifications，i．e．，YJ V，YJ V22．If you want the weight of YJ LV，YJLV22，you can
    find out according to the following formula：(the overall diameter is the same)．
    WL=Wcu-S·K(ρcu-ρL)
    WL=weight of AL core cable(kg/km) Wcu=weight of copper core cable(kg/km)
    S=corresponding nominal cross - section of copper and AL cores mm2
    K=twist coefficient（1.00-1.012）     ρcu=copper density(8.9g/cm3)     ρL-AL density(2.7g／cm3)
(2)If you want to know the overall diameter and weight of steel wire armor，see the following：
    Overall diameter of steel wire armored cable=(1.08-1.16)times the steel belt armored cable overall diameter(mm)．
     Weight of steel wire armored cable=(1.2-1.5)times the steel belt armored cable weight．
(3) Parameters in the following tables have carried out round number correction on the foundation of technological parameters.
