Metal Shielding Power Cable

Metal Shielding Power Cable

1.Scope ofapplication

It is used for power transmission on power lines of rated voltage0.6/1kV or lower.lt has strong resistant characters againstelectromagnetic interference, thunder strike and even electricpotential, improving power sup- ply quality. It is especially suitableto place with precision electronic devices such as computercenter, space & aviation supervision center and intellectualbuildings etc.

2.Executive standard

Enterprise standard

3.Type and Description

Note: 

1: We also produce cable with fame resistant performance or fire resistant performance accordina to the reauirement of customerPrefix “ZR-”should be added to the original type for flame retardant cable and “NH-" added for fire-resistant cable.

2: There are two kinds of metallic shielding. One is metallic wire braiding shielding. The other is metallic tape wrapped shielding.

3: Prefix“R”should be added to the original type for ordering cable with soft conductor;

4.Specification

5.Working Condition

1: Max long-term working temperature allowed by conductor is70℃ for cable with PVC insulation, 90℃ for cable with XLPE insulation

2: Max temperature of conductor is no higher than160℃ for cablewith PVC insulation, 250℃ for cable with XLPE insulation duringshort circuit (The longest lasting time is no more than 5s).

3: Environment temperature for installation is not lower than 0℃

4: Bending radius allowed by cable is no less than 20 times that ofcable outer diameter for armored cable, 15 times that for inarmoredcable, 10times that for cable with soft conductor

6.Approximate Outer Diameter of Cable

Outer diameter value of VVP type and VLVP type cable shouldbe added by 1~1.5mm² on the basis of that of VV type and VLV typecable.

Outer diameter value of YJVP type and YJLVP type cable shouldbe added by 1~1.5mm²on the basis of that of YJV type and YJLVtype cable.

Outer diameter value of VV22P type and VLV22P type cableshould be added by1.5mm² on the basis of that of VV22 type andVLV22 type cable.

Outer diameter value of YJV22P type and YJLV22P type cableshould be added by 1.5mm²on the basis of that of YJV22 typeand YJLV22 type cable.

7.Main Technical Parameter

1: DC resistance of conductor at 20C

2:Insulated resistance

3: Finished cable should endure A.C voltage test of 3.5kV, AC50Hz for 5min without puncture.

4: Fire resistant performance of fire resistance cable should meettesting requirement of category A or B stipu- lated in IEC60331or GB12666.6 standard.

5: Flame retardant performance of Flame retardant cable shouldmeet testing requirement of category A or B or C stipulated inIEC60332 or GB/T18380.3standard.
