Brief introduction

With the high-speed development of economy, moder buildings is changing daily, the complication ofconstruction distribution has became a big subject popular concerned by construction design, invest andconstruction unit.In order to meet the need of the market, and catch up with world's advanced technologythe birth of the Precast Branch Cable brings a new choice for the power supply line in the building.

Main features of FZ series prefabricated branch cable

1.Excellent reliability of power supply safety

2.Simpleness in installation,low requirement to environment,and convenience in construction

3.Excellent shock resistance, air sealing，water proof and flame resistance

4.Free of maintenance

5.Distinctly reducing electric distribution cost

6.Multiple categories and specifcations， flexible option， and combination at Will.

Variety and model of FZ series prefabricated branch cable

Optional variety and specifications of cable:
YJV: XLPE insulated and PVC sheathed power cable.
ZR-YJV: XLPE insulated and PVC sheathed flame retardant power cable.
NH-YJV: XLPE insulated and PVC sheathed slow-burning power cable.
VV:PVC insulated and sheathed power cable.
ZR-VV: PVC insulated and sheathed flame retardant power cable.
NH-VV: PVC insulated and sheathed slow-burning power cable.
GWDZ-, WDZA-, WDN-, WDZAN-: the new generation of polyolefin sheathed power cable with lowsmoke,
low toxicity and halogen free.

G-oxygen series cable

Notes:
1. The cable is single core copper cable with 0.6/lkV rated voltage (UO/U) without special indication.
2 The main cables are electric ones applying black protection cover.
3. Without special indication, the branch cables all apply the same type of electric ones as the main cables4. If the branch cable requires model BV-500 wire with colour marks (vellow. red, green, light, blue.yellow/green).It should be specified during ordering.

Variety, type and specification

Standard of main cable and branch cable all takes XLPE or PVC as insulation(lEC, GB, JIS,
BS ) .low electricpower cable is material PVC packaged.Average trunk cablc is single core or more core twist type cable(twocore to five core ofcable),single core cable of branch cablemay according to need to adopt fire-resistant, flame resistant capability of cable.

Main features of FZ series prefabricated branch cable

1.Insulation resistance >200MQ;

2.InsulatiOn withstand Voltage>3.5kV/5min;

3.Excellent air tightness and water proofing quality. When immerge branch joint water, measured insulationresistance between water and cable core, and power frequency withstand voltage meet the requirement ofitems 1 and2.

4.Little contact resistance of branch joint. The ratio value of contact resistance vs reterence resistance ofequal length branch line is equal to or less than 1.2;

5.Large joint short circuit strength. The variation rate of contact resistance ratio after short circuit is equal to orless than 0.2;

6. For ZR-YJV type flame-retarded prefabricated branch cable, self extinguishing time of jacket is equal to orless than 12s and meets GB/T18380.3;

7. Besides power supply in normal working condition. NH fire resistance type cable can reamin normaloperation for 90min under buming condition and meets GB/T19216.21-2003;

8.Max. working temperature of copper, core of VV type cable is 70'C and that of YJV type cable 90'C;

9.With excellent corrosive resistance. it can keep from eroding of inorganic salt, oil, base, acid, organicsolution and so on;

10. YJV type prefabricated branch cable has excellent themal stability and aging resistance;

11.GWDZ-, WDZA-, WDNA-, WDZAN-clean-type precast branch cable possesses the features suchas lowsmokelow-toxic,non-halogen and fire-resistance etc;

12.GZR-YJV oxygen barrier branch cable with high flame retardant and fire resistance that exceedsAntifaming Stamdard A class.

The pre-branched cable consists of four parts: 1. Trunk cable; 2. Branch line; 3. Branch connector: 4. Related accessories, and has three types: ordinary type, flame-retardant type (ZR), and fire-resistant type (NH). Pre-branch cable is a substitute product for busway power supply in high-rise buildings. It has the advantages of reliable power supply, convenient installation, good waterproof, small building area, low failure rate, cheap price, and maintenance-free. It is suitable for AC rated voltage of 0.6/1KV distribution lines. Widely used in vertical power supply in high and middle-rise buildings, residential buildings, commercial buildings, hotels, hospitals, electrical shafts, and also suitable for power supply systems in tunnels, airports, bridges, highways, etc.
