PVC is widely used in cable industry i.e. cable sheath and insulation because of economic and good electrical and mechanical pe
Crosslinkable polyethylene widely used for cable insulation of middle and high voltage.
>> Silane XLPE is used for 10kv or below cable insulation.
We not only have compounding and pelletizing system for two-step porcess, but also have one-pack system which is updated process and is already used in our customers factory.
>Two pack processing system
This is a typical process that is to make Compound A (grafted PE) with a long L/D ratio twin screw extruder, and use a small twin screw extruder for making Compound B (Catalyst), finally the finished Compound A and Compound B will be packed with seprated vacuum bags for the downstream silane xlpe cable extrusion.
The main parts include twin screw extruder, gravimetric feeder, pelletizing system and vacuum packing system.
>One pack processing system
We coperate with Shanghai Wire & Cable Research Institute and seek a simplied process for Silane XLPE compound, now it is proved sucessful by our users.
It only needs a middle size twin screw extruder, simple strand pelletizing system and our special rotary mixing system, which helps our users to reducing the equipment costs and simplify the operation and process.
>> Peroxide XLPE is used for 10kv-35kv cable insulation or110-500kv extra-high voltage cable insulation
Our CMS series reciprocating kneader(co kneader/BUSS kneader) is the best solution for peroxide XLPE, the high end users are prefer to reciprocating kneader(co kneader/BUSS kneader), but SDJ series two stage twin screw and single screw extruder is more popular in China and Asia, because the cost of the machineries are economic.
