Advantages and disadvantages of rubber cables

1. Advantages and disadvantages of general rubber sheathed flexible cable: General rubber sheathed flexible cable is widely used in industrial and agricultural and daily electrical as a mobile power line connecting electrical devices, which can be used outdoors and outdoors in various environments, according to the external force, the product is divided into medium and heavy two forms:

1) Medium-sized cable: should have enough flexibility to facilitate movement, bending, light cable weight, small outer diameter, very convenient to use, generally do not bear the action of external force.

2) Heavy-duty cable: should be able to withstand large mechanical external forces (extrusion, impact). The sheath has high mechanical properties, good wear resistance and elasticity, and should also have a certain degree of softness to facilitate bending and moving.

The general rubber sheathed flexible cable moves frequently, and is often subjected to mechanical external forces such as bending, torsion, friction and so on in use, all requiring the cable to be soft and wear-resistant. And often contact with oil, outdoor use of cables must also withstand sunlight, so this kind of cable is also required to have sun aging resistance, oil resistance and moisture resistance.

2. Advantages and disadvantages of mining rubber cable: mining rubber cable is widely used in coal mines and other mines, and there are a large number of combustible and flammable substances such as gas and dust in mine shafts; Electrical safety requirements are extremely strict, and the mine is wet and potentially corrosive. Cables move frequently and are often subjected to bending, twisting, dragging and crushing impacts. The cables used in the open field must also be able to withstand the action of sunlight, so the requirements for mining cables are particularly strict. The conductive wire core should have a high degree of flexibility, and finer soft copper wires are often used to twist with a small pitch. The insulation layer should have high electrical resistance and mechanical strength. The cable is required to be soft, wear-resistant, impact-resistant, bent frequently and frequently, and also have good flame retardant performance. The cable sheath is much thicker than the sheath of the general-purpose rubber sheathed flexible cable to increase the impact resistance and crushing resistance of the cable.

3, welding machine cable advantages and disadvantages: welding machine cable is low voltage, high current, frequent movement, often torsion, bending, dragging and other effects in use, the use environment may have acid, alkali, oil, etc., so the welding machine cable requires that the conductive core should be very soft, the insulation should be flame retardant, and the sheath should have wear resistance, oil resistance, atmospheric aging resistance and other properties.

4. Advantages and disadvantages of waterproof rubber cable: Waterproof rubber cable is mainly suitable for AC voltage 450/750V and below submersible motor or submersible pump connected to the power supply, can also be used for oil pollution occasions.
