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;

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.
