YJ-FD系列预置分支电缆的主要优点:
▲具有优良的供电安全可靠性
1、主干电缆导体无接头，连续型号，减少了故障点。
2、分支街头采用工厂全程机械化制作，大大降低了人为因素造成质量不良现象。
3、分支接头结构合理并采用先进的LYZ工艺制作，接触电阻极小，不受热胀冷缩影响。
4、短时间内完成压模护套，避免了接头接触铜芯长时间裸露在空气中产生氧化导致接触电阻变化。
5、分支接头有严格的技术标准和检验要求，以及严密的质保体系。
▲安装简便环境要求低，施工方便
1、占用建筑面积小，有利于建筑面积的有效使用。
2、使用环境要求低，安装精度要求低。
3、安装简单方便，安装技术要求不高，安装周期短，仅为母线槽安装工时的1/10或1/20。安装劳动强度小。
4、由于他的弯曲半径小，大大地降低了安装难度和缩小了空间尺寸。
▲优良的抗震性、气密性、防水性和耐火性
1、优良的抗震性，一般机械连接母线槽接头，在墙体受震动后会发生接头松动，而YJ-FD系列预置分支电缆不会受到影响。特别在通过建筑沉降缝时不需要任何措施。
2、良好的气密性和防水性，能在潮湿的环境中正常供电，也能在露天及埋地敷设使用，但母线槽绝对不能做到。
3、采用“NH”型的预置分支电缆，可在燃烧情况下，保持90min的正常供电运行。
▲免维护
1、预置分支电缆按规定方法安装后，一次性开通率高。
2、正常运行的预置分支电缆系统平时不需要任何维护保养。
▲可明显降低配电成本
1、与母线槽相比，可降低工程造价，且技术经济指标高，综合经济效益显著。
▲品种规格多，选用灵活，任意组合
1、主电缆从10mm2到1200mm2，分支电缆从4mm2到300mm2任意组合选用。
2、电缆品种多，有VV、ZR-VV、NH-VV、YJV、ZR-YJV、NH-YJV、GZR-YJV、GDL-YJV、GWL-YJV、GWL-YJE、GNH-YJV、GNH-YJE等，可根据需要选用。
3、分支接头可根据楼层需要任意设定分支位置。
Main characteristics of YJ-FD series prefabricated branch cableh
▲Safety in power supply
1.Trunk cable conductor without joint has good continuity and reduces trouble spots.
2.Branch joint made through whole course mechanical processing in the factory greatly reduces poot quality phenomena due to man-made factors.
3.Branch joint of rational struture and made through advanced LYZ workmanship has little contact resistance and connot be affected by thermal expansion and cold shrinkage.
4.Pressing mould jacket processed in short time avoids variation of contact resistance owing to oxidization of copper core at the joint posistion which is exposed in the air for long time.
5.Branch joint has strict technical standard,inspection requirement,andquality control system as well.
▲Simpleness in installation,low requirement to environment,and convenience in construction.
1.Small land-covering area facilitates effective use of floorage.There is no requirement to land construction space.
2.Low requirement to environment and low requirement to installation precision.
3.Simpleness in installation and low requirement to installation rechnology.Referring to installation equipment,a normal widlass is enough. Theinstallation period is short only 1/10 or 1/20 of that of bus duct.The labor strength for installation is small.
4.Small bending radius greatlly reduces installation difficulty and reduce space size.
▲Excellent shock resistance,air tightness,water proofing quality and flame resistance
1.Excellent shock resistance.Generally,the bus duct joint connected mechanically will be loose upon the wall is shocked,But YJ-FD series prefabricated branch cable will not be affected.Especially passing
through building sedimentation slots,no measure is need.
2.Excellent air tightness and water proofing quality.It can supply power
normally in damp environment and be laid in the open air or underground.
3.NH type perfabricated branch cable can remain normal power supply operation for 90min under flaming condition.
▲Free of maintenance
1.High once opening rate of prefabricated branch cable after being installed according to stipulated ways.
2.While normally work,prefabricated branch cables system is free of maintenance generally.The fault rate is zero.
▲Distinctly reducing electric disribution cost
1.In comparison with bus duct, it can reduce engineering cost,and has high technical and economical index,and remarkable comprehensive economic result.
▲Multiple categrories and specifications,flexible option,and combination at will
1.Main cable from 10mm2to 1200mm2and branch cable from 4mm2to 300 mm2can be combined at will.
2.Multiple cable categories,e.g.VV,ZR-VV,NH-VV,YJV,ZR-YJV,NH-YJV,GZR-YJV,GDL-YJV,GWL-YJV,GWL-YJE,GNH-YJV,GNH-YJE etc.Can be chosenaccording to the demand.
3.Branch joint can be set up branch positions at will according to the floor requirement.
YJ-FD预制多芯分支电缆
YJ-FD The multicore prefab-ricated branch cable
根据用户的实际需要和市场需求状况，本公司在单芯预制分支电缆的技术基础上，又开发了三相五线等多芯预制分支电缆系列产品，它主要应用于工厂、中高层建筑等照明和动力用电。
由于多芯电缆外径大，重量重，制成预制分支电缆时外径更大，这样会造成敷设困难。因此我公司目前生产的最大多锌预制分支电缆限制在4×240+1×120及以下的产品。品种也有普通型、阻燃型、耐火型、隔氧层阻燃耐火型等不同截面电缆。多芯预制分支电缆的安装方式与单芯分支电缆相似。
According to actual demands of users,Company has developed series products of three-phase four-wire and other multicore prefabricated branch cable on the basis of single-coreprefabricated branch cable.They are minly applied to lighting and dynamic electricity of factory and middle/high building. Because multicore cable has large outside diameter and heavy weight,after it is made to preset branch cable,the outside diameter will be larger and result in difficulty in laying.Therefore,the largest multicore prefabricated branch cable manufactured by our company is restricted below 240mm2 .There are a varirty of flame retardedtype and fireproof type in equal or different section.
If you adopt branch wire of different sections,you can choose single-core prefabricated branch wire.Current carring capacity of multicore prefabricated branch cable is the same to that of multicore cable,and the installing method is similar to that of multicore cable.

为了适应我国国民经济的迅速发展，各大城市兴建的城市基础设施建设及大量的住宅楼宇和写字楼宇兴起，在用电和照明等方面都需要一种既适应上述建筑输配电要求，又要安装方便的特殊输配电产品。
为适应上述需求，本公司开发、研制出符合环保要求的大截面铠装预制多芯分支电缆，并已投入批量生产。型号规格有：普通型、交联型、阻燃型
耐火型、安全清洁型、隔氧层阻燃耐火型。电缆最大截面可达：240mm2/相；分支载面可按用户要求生产。
In order to adapt to the fast development of national economy.and the construction of lots of infrastructures as well as residential buildings and office buildings,the special transmission and distribution that meet above-mentioned constructions and is featured with the convenience of installation are demanded urgently in the field of power utilization and illuminating.
Because multicore cable has large outside diameter and heavy weight,after it is made to preset branch cable,the outside diameter will be larger and result in difficulty in laying.Therefore,the largest multicore prefabricated branch cable manufactured by our company is restricted below 240mm2 .There are a varirty of flame retardedtype and fireproof type in equal or different section.
At present,the branch wire of multicore prefabricated branch cable can only be a grade section in a loop. If you adopt branch wire of different sections,you can choose single-core prefabricated branch wire.Current carring capacity of multicore prefabricated branch cable is the same to that of multicore cable,and the installing method is similar to that of multicore cable.
