Description
1. The rubber sheathed cable has the advantage of occupying a
smaller area. More traditional power cables appear on the ground,
forming a Spider web, which affects our life and is not beautiful
at the same time. Nowadays, power cables are mostly buried
underground, which effectively saves space on the ground and is
also more aesthetically pleasing.
2. Reliability is becoming increasingly prominent. With fierce
competition in the market, the performance of rubber sheathed
cables continues to break through, especially in terms of
reliability. They can be applied in different harsh environments
and are stable and reliable in transmitting electricity, thus
winning widespread market demand.
3. Rubber sheathed cables have the characteristic of being
high-voltage, and nowadays, low-temperature and superconducting
rubber sheathed cables are more commonly seen in the market, which
also stimulates the rapid development of large capacity rubber
sheathed cables due to the increase in electricity consumption.
4. The advantages of rubber sheathed cables, such as larger
distributed capacitance, less maintenance workload, and low click
probability, have led to an increase in product market sales.
1. The surface of rubber sheathed cables may not be smooth due to
the mold sleeve bearing wire being too long or too short, the mold
mouth not being smooth, and the aperture being too large; The
temperature of the machine head, die mouth, or body is low; Low
plasticity of rubber materials and other conditions may cause
it.
2. The supplied rubber is not clean and contains impurities; The
scorching time of the rubber material is too short; The temperature
of the extruder body, head, or die is too high; The rubber flow
inside the machine head is not smooth, and there are dead spots
where the rubber material is stuck; Unsmooth screws, adhesive, etc.
may cause the appearance of clinker particles (early vulcanized
rubber particles) or impurities on the surface of rubber sheathed
cables.
3. The mold sleeve is not smooth and has no chamfers; There are
impurities or cooked rubber particles blocking the mold opening;
Scratches caused by dragging the tube inside the vulcanized tube;
The small aperture of the sealing rubber gasket at the outlet of
the vulcanized tube may cause scratches and scratches on the
surface of the rubber sheathed cable.
4. The aperture of the mold sleeve is too large; The gap between
the outer layers of the conductive wire core and between the single
wires is too large, and the outer diameter of the cable core is
uneven; Rubber has low plasticity and poor viscosity; Impurities in
the rubber material; Small distance to the mold, low pressure, and
other factors may cause the surface of the rubber sheathed cable to
collapse.
5. The aperture of the mold sleeve is too small; Insufficient
extrusion of rubber material, insufficient filling of wire core
gaps; Conductive core or cable core jumper; The short distance
between two molds may cause Fried Dough Twists on the surface of
the rubber sheathed cable.
