Description of the use and performance of the control line

The control cable should meet the requirements of GB/T9330-2008. 450/750V PVC insulated control cable, flame retardant PVC/XLPE insulated control cable and refractory PVC/XLPE insulated control cable.

450/750V polyethylene insulated control cable meets the requirements of GB/T9330-2008.

The 450/750V XLPE insulated control cable complies with the relevant provisions of GB/T9330-2008.

The electrical performance of the flame-retardant and fire-resistant control cables complies with GB/T9330-2008 "Plastic Insulation Control Cable", and the flame-retardant performance meets the requirements of GB/T19666-2005 "General Rules for Flame Retardant and Fire-Resistant Wire and Cable" according to requirements.

Control Cable Uses Attention To Process And Features:

DC Resistance

20 ° C, 0.4 mm copper wire, less than or equal to 148 Ω / km, 0.5 mm copper wire, less than or equal to 95 Ω / km.

Insulation Electrical Strength

1min 1kv between conductors does not break down the conductor and shield 1min3kv does not break down.

Insulation Resistance

Each core wire is grounded with the other cores, the control cable is more significant than 10000 MΩ.km, and the HYAT cable is more important than 3000 MΩ.km.

Working Capacitance

Average 52±2nF/km.

Far-end Crosstalk

The average power of the specified combination is greater than 69dB/km at 150kHZ.

Precautions For Controlling Cable Installation And Wiring:

Under The Eaves

The standard LAN cable can be used only when the cable is not directly exposed to sunlight or high temperature. It is recommended to use the pipe. Ultraviolet (UV)--Do not apply UV-free lines to direct sunlight.

The Outer Wall

Avoid direct sunlight on the wall and human damage. Heat - The temperature of the cable in metal pipes or trunking is high and many polymeric materials will reduce their service life at this temperature.

In The Pipe (Plastic Or Metal)

For example, in the pipeline, pay attention to the damage to the plastic pipe and the heat conduction of the metal pipe.

Suspended Application/Overhead Cable

Consider the drooping and pressure of the line and whether the cable is directly exposed to sunlight.

Lay Directly In The Underground Cable Trench

This environment is the smallest control area. Cable trench installation should be checked regularly for dryness or humidity. 

Grounding - If the shield of the control cable needs to be grounded, the corresponding standard must be observed.
