Precautions for installing cables in spring


Cables are the main equipment for transmitting electrical energy and electrical signals. The installation of cables has a bearing on the safety of electricity and workers. Henan wire and cable manufacturers remind you that the following issues should be noted when installing cables in spring.

When installing the cable in spring, you should try to avoid installing the cable in windy weather, especially outdoor or in the wilderness. Excessive wind can easily threaten the safety of workers. Wire and cable manufacturers recommend that workers pay attention to wearing safety gear and fasten their seat belts when installing at high altitudes. Work at high altitudes and even in dusty weather should be prohibited to prevent accidents.

It is also not suitable for construction in rainy days, because the cable is prone to short circuit or even fire accidents when it is wet. If the construction period is urgent, the wire and cable manufacturer recommends that you construct the tent at the construction site. After the construction is completed, you should carefully check the connection part of the cable to prevent the connection from being tight or even the wire exposed. In addition, the cable connection part and the terminal part must be tightly wrapped to prevent moisture and short circuit.

Analysis on the causes of defects in the appearance of rubber sheathed cables


Rubber-sheathed cables are common wires and cables in our daily life. When wire and cable manufacturers produce rubber-sheathed cables, they will encounter appearance defects. Let us look for the reasons together.

One of the appearance defects found in the production of wire and cable manufacturers is the long or short length of the rubber-sheathed cable, the mating port is not smooth, and the hole diameter is too large. The cause of this situation is the low temperature of the head, body or die. ; Small plastic and so on; Henan wire and cable.

The cause of clinker particles or impurities on the surface of the rubber sheathed cable is that the rubber material contains impurities; the rubber scorch time is insufficient; the temperature of the machine head, the body and the die is too high; the rubber flow in the machine head is not smooth, and some rubber materials are retained Dead angle; screw is not smooth and sticky;

The mold sleeve is not smooth and there is no chamfer; the mold mouth is blocked by impurities or cooked rubber particles; there is pipeline abrasion in the vulcanization tube; the rubber seal gasket outlet diameter of the vulcanization tube is too small, which causes scratches and abrasions on the surface of the rubber cable;

The reasons for the surface collapse of the rubber-sheathed cable include the too large aperture of the mold sleeve; the pores between the outer strands of the conductive core and the monofilaments are too large, and the outer diameter of the cable core is not uniform; the rubber has low plasticity and poor viscosity; the rubber is not clean; The distance to the die is small; the pressure is small; Henan wire and cable.

Hemp pattern appears on the surface of the rubber sheathed cable: the diameter of the mold sleeve is too small; the rubber material is insufficiently squeezed, and the core gap is not filled; the conductive core or the cable core jumper; the distance to the mold is short.
