Product Details

Computer shielded cables for intrinsically safe circuits
1： Product Features and Applications

This product has low capacitance and low inductance, excellent shielding and anti-interference performance. The special high-temperature computer cable is made of imported fluoroplastics and fluororubber materials, and can be used for a long time in an environment of -40-260 ℃. The product has the characteristics of non flammable, acid, alkali and oil-water resistance. The cable structure is specially designed for intrinsically safe explosion-proof circuits, not only for bridge laying, but also for cable trench laying and direct burial laying. The special high-temperature intrinsically safe computer cable obtained the national certificate in 2000. Suitable for use as transmission lines in distributed systems and automated detection systems with explosion-proof protection requirements and other harsh environments, the explosion-proof safety is significantly higher than that of general DCS cables and computer control cables.

2： Product execution standards

Q/HHTZH002.4 (Equivalent to British BS5308 standard)

Flame retardant according to GB12666-90 standard

3： Use special

1. Rated AC voltage: U0/U 300/500kV

2. Maximum working temperature: Polyethylene insulation not exceeding 70 ℃

Cross linked polyethylene insulation at 90 ℃

Low smoke halogen-free flame-retardant polyolefin at 70 ℃

Low smoke halogen-free flame-retardant cross-linked polyolefin at 90 ℃ and 125 ℃

Perfluoroethylene propylene (F46) insulation not exceeding 200 ℃

3. Lowest ambient temperature: PVC sheath: fixed installation -40 ℃, non fixed installation -15 ℃

Fluoroplastic and silicone rubber sheath: fixed installation -60 ℃, non fixed installation -25 ℃.

4. The temperature for cable installation and laying should not be lower than 0 ℃ (high temperature type should not be lower than -25 ℃).

5. Allowable bending radius for cables: The minimum allowable bending radius for non armored cables is 6 times the outer diameter of the cable

Copper tape shielded or steel tape armored cables with a minimum diameter of 12 times the outer diameter of the cable

4： Basic model and name

1. Polyethylene insulated PVC sheathed intrinsically safe circuit and computer shielded cable (including intrinsically safe DCS cable)

IA-DJYPV? P	Polyethylene insulated copper wire braided split screen total screen PVC sheathed intrinsically safe computer shielded (flexible) cable
