Semiconducting PVCJacketing Compound for High Voltage Cable
I. Typeand application
Type | Product | Application and Cable Specification |
VB-35A | Semiconducting PVC Jacketing Compound for High Voltage Cable | Applying to high voltage cables and other area cables as jacketing compound |
VBZ-35A | Semiconducting Flame retardant PVC Jacketing Compound for High Voltage Cable | Applying to high voltage cables and other area cables as flame retardant jacketing compound |
II. ProductDescription
Theseproducts used PVC resin as base materials, and added nanometer conductivecarbon black as filling, by mixing, plasticizing, pelleting, and finished aspellets. These products have very good conductive and processingcharacteristics. And it mainly substituted the graphite coat structure.
In theformula, it decreased the affect of plasticizer to conductive carbon black bythe technology of toughness reinforcing. At the same time, reduced the affectof materials low temperature and processing properties, because adding masscarbon black in the products. And we selected suitable low temperatureadditiver and rheological agent to improve the PVC materials, and made it hasgood integrated properties.
III. Processing
Use singlescrew extruder to process, suggest to put one layer 60/80 strainer.
Thefollowing temperature(℃) profile of extruder is recommended:
Zone | Zone 1 | Zone 2 | Zone 3 | Zone 4 | Zone 5 | head | Die1 | Die2 |
Temperature ℃ | 140 | 155 | 160 | 165 | 170 | 170 | 170 | 170 |
Note:Above information just for you refer, please adjust it according to equipmentconditions and extruding situation.
IV. Storageand transport
Packaging:25kg/bag,Aluminumfoil vacuum and moistureproof inside bag and complex Kraft outside bag.
Storage and transport: Avoiding indirect sunlight and weathering. The storage place should be in clean, cool,dry, and ventilated conditions.
