CE self-regulating heating cable

self-regulating heating cables good heating system CE ,ROHS, GOST approved best heating cable

Cable structure:

1. Copper-core wire: 7×0.50, 7×0.32, 19×0.41

2. Conductive plastic layer: common PTC, fire-retardant PTC, fluorin-contained PTC

3. Insulation layer: modified polyolefin, fire-retardant polyolefin, fluorin-contained polyolefin, fluorin material

4. Shielding layer: soft round tinning copper braid, covering density: 80%

5. Restrictive coating: modified polyolefin, fire-retardant polyolefin, fluorin-contained polyolefin, fluorin material

Specifications:

1. Standard color: brown

2. Temperature range:

Max. Working Temperature 105±5°C

Max. Exposure Temperature 135°C

Max. Enduring Temperature: modified polyolefin: 105°C;

Fire-retardant polyolefin: 105°C;

Fluorin-contained polyolefin: 180°C;

fluorin material: 205°C

3. Minimum installation temperature: -40°C

4. Start-up current (at 10°C): ≤0.7A/m

5. Thermal stability: After circulating for 300times from 10°Cto 149°C,the heat of cable is maintained above 90%.

6. Minimum bend radius: At -20°C:38.5mm

                                       At -30°C:49.0mm

7. Insulation resistance: Testing insulation resistance is 20MΩ at least if cable length is 100m and thermostatic water is 75°C. As for shielding or explosive-proof & protective type, test for 1 min between shielding layer and conductive wire core in 2,500VDC in 20°C, insulation resistance is 1200MΩ at least.

Advantage1. Equal temperature  safe and reliable. 2. Save electric energy. 3. Rapidly Temperature increase4. Low cost of installation and operation  5. Easy to install and maintain. 6. Convenient for automatic management. 7. No pollute environment
