CONTROL CABLE

1 PVC insulated & sheathed control cable

1.1 PVC insulated & sheathed control cable is suitable for connecting wires between electric equipments in controlling, monitoring loop and protecting circuit at rated voltage up to and including 600/100V (A.C.). The product has not only excellent characteristics in electric and mechanical purpose but also in performances of chemical corrosion resistance, heat-aging, environmental stress and flame-retardant. The product has simple construction and convenient to use and could be laid with no restriction of different levels.

Our product of  PVC insulated and sheathed control cable can be manufactured according to the Chinese Standard GB9330-88, which was complied with reference to IEC227, IEC502 and the Standards of Germany , American, Japan and U.S.S.R for control cable .

1.2 Flame-retardant control cable

Flame-retardant  control cable is suitable for connecting wires between electric equipments with a special flame-retardant requirement in controlling, monitoring loop and protecting circuit at rated voltage up to 600/1000V(A.C.). Our flame-retardant control cable includes A class flame-retardant control cable, special flame-retardant control cable, low smoke halogen free flame-retardant control cable, low smoke low halogen flame-retardant control cable, XLPE insulated control cable and XLPE insulated flame-retardant control cable.

2 Applications

2.1 Rated voltage U0/U should be 450/750 V~600/1000V

U0~Valid value of the voltage between main insulated conductor and earthing (metal shield, metal sheath of environment dielectric).

U~valid value of voltage between any two phases conductor in multicourse cable or single core cable system.

When AC. System is applied, the rated voltage of cables should be at least equal to the nominal voltage of the system. When DC. System is applied; the nominal voltage of this system should not be more than the rated voltage of the system by 1.5 times.

2.2 The permitting long-term operating temperature of cable conductor should be

PVC insulation: 70

Chemical Sioplascable: 90

Irradiation XLPE :105~135

2.3 The installing temperature of cable should not be less than 0. Recommending permitted bending radius:

Non-armored cable: not less than the overall diameter f cable by 6 times

Shielded flexible cable: not less than the overall diameter of cable by 6 times

2.4 The performances of electric and physical machinery shall be conform to the requirements of Chinese Standard GB9330Plastic insulation armoured cable.

2.5 The flame-retardant performance of flame-retardant armoured cable shall be conform to the requirements of Test method for electric cable and wire(same as IEC332).

2.6 Characteristic of low smoke halogen free (only for low smoke halogen free flame-retardant armoured cable).

Halogen free performance : conform to the requirement of IEC754Hydrogen-halogen acid gas quantity test.

Low smoke character performanceconfirm to the requirement of GB12666.7Gas consistence of Wire and cable buring test.

Low toxicity performance: conform to requirement of NES713Measurement of toxicity index.

5 Distinguish of insulated and arrange drawing

5.1 Colors distinguish

   Colors distinguish for insulated core of 5 cores and below

5.2 For the cable distinguished by digits, the colours of insulation and digits marks should be different distinctly so that it is easy to separate the cores in installing.  The colour of insulation should be black, white, yellow, corresponding digits colour is white, black (blue), black (blue) etc.
