Locomotive Cable Compound:
1. Applications and cable specifications:
Applied to the locomotive cables which voltage is less than 3KV and temperature is 125°C.And the cable is used in the no mineral oil and no fuel oil environment.
2. Description:
Irradiation cross-linkable, low smoke halogen free and flame retardant POE compound for locomotive cables, based on special high oil resistant POE resin, is produced and pelletized by special technology with adding special stabilizing agent, modifier, halogen free flame retardant, cross-linking agent, antioxidant and other special additives. It meets the locomotive cable requirements of high temperature resistant and oil resistant.
3. Processing:
Irradiated dosage:12-15 megarad
The compound can be processed with conventional extruders, and the normal PVC screw with a minimum 20:1 L/D. It is better if use low compression ratio screw.
The following temperature(°C) profile of extruder is recommended:
| Zone | Zone 1 | Zone 2 | Zone 3 | Zone 4 | Head | Die |
| temperature °C | 130 | 145 | 150 | 150 | 145 | 145 |
4. Storage and transport:
Packing: 25kg/bag, PE membrane inside bag and craft outside bag.
Avoiding in direct sunlight and weathering.
Storage place should be clean, cool, dry and ventilated.
