A cable compound is a material, usually petroleum-based, used to fill an electrical cable to limit intrusion from water and to provide extra insulation. Numerous types of cable including electrical and phone lines can be filled with cable compounds by manufacturers and installers to protect the integrity of the line. The cable is also tightly jacketed to add another layer of insulation and protection and to increase the duration between maintenance sessions, as the cable should remain stable and durable for an extended period of time with the extra protection.
Resins, fillers, and additives are mixed and processed through a twin-screw extruder to produce pellets, which serve as raw materials for making wires and cables.

Product Parameters

DMTT series extruders is defined as a two-stage model, The first stage is high-speed twin screw extruder, the second stage is low speed single screw extruder. The two extruder are arranged in a T-shape, forming a two-stage compound unit. It is widely used in all kinds of heat-sensitive material system and large capacity deashing.

The combination of twin screw and single screw can decompose the process function and increase the independent operation variable, which is beneficial to the step optimization of each process. Improved efficiency and capacity.
