5- Cable structure description

Cable structure

Material Description

Conductor

Class 1 solid copper conductor or Class 2 round stranded copper conductor or Class 5 soft copper conductor

Fire-resistant layer (if any）

Mica tape

Insulation

Polyvinyl chloride or polyethylene or cross-linked polyethylene or halogen-free low-smoke polyolefin

Twisted pair, group or star twist tape (if available)

Polyester tape or non-woven fabric

Individual shielding (if any)

Copper wire braid or (copper tape or copper plastic tape or aluminum plastic tape) wrapping or aluminum plastic tape wrapping and copper wire braid composite shielding

Filling

Non-hygroscopic Polypropylene Reticulated Filler Rope

Cable wrapping tape

Non-woven fabric or polyester tape

Overall shielding (if any)

Copper wire braid or (copper tape or copper plastic tape or aluminum plastic tape) wrapping or aluminum plastic tape wrapping and copper wire braid composite shielding

Inner sheath or isolation sleeve (if any)

Polyvinyl Chloride (PVC), Polyethylene (PE), or Halogen-free Low-smoke Polyolefin Sheathing Compound

Armor (if any)

Galvanized steel strip or galvanized steel wire

Outer sheath

Polyvinyl chloride or polyethylene or halogen-free low-smoke polyolefin

6-Wire core identification

Cable components are identified by insulation coloring, and different colors are used to distinguish the strands within the pairs (groups). Different color spectra, color bands, or numbers can be used to distinguish and identify the wire groups, or according to customer requirements.

7-Sheath color

Black or as per customer's requirement

8-Special performance requirements

Flame retardant A/B/C grade, fire resistant, low smoke and halogen-free, termite-proof, rodent-proof, UV-resistant, mineral oil-resistant, etc.

9- Cable application characteristics

9.1 The maximum long-term rated temperature allowed for the cable conductor during normal operation:

PVC insulation, polyethylene insulation, low-smoke halogen-free polyolefin insulation: 70°C; cross-linked polyethylene insulation: 90°C.

9.2 The cable installation temperature should not be lower than 0 ℃

9.3 Minimum bending radius for cable installation:

For non-armored cables or copper wire braided shielded flexible cables: the bending radius shall not be less than 6 times the outer diameter of the cable;

Cables with copper tape or copper-plastic tape shield or aluminum-plastic tape shield or steel tape armor or steel wire armor:

The bending radius shall not be less than 12 times the outer diameter of the cable.

9.4 This cable is widely used in industrial automation instrumentation and control systems (ICS) , distributed control systems (DCS) , and programmable logic controllers (PLC) with a rated voltage of 300/500V . As a connecting line between electronic computers, industrial automation instruments, sensors, and actuators, it enables the automatic control of analog and digital signal systems such as detection, control, alarm, and interlocking, and transmits analog and digital signals such as detection, control, interlocking, and alarm for process variables in production equipment. It has excellent resistance to magnetic field interference, electrostatic interference, and is resistant to insect and bird damage. It can be installed indoors , outdoors , directly buried , or in cable conduits and trenches.
