How to solve the problem of cable heating


Cable joint heating is the most common phenomenon in the use of cables. This phenomenon will not only cause a large amount of power loss, but also affect the insulation and conductor of cables, which will shorten the cable life, and lead to fire and electric shock accidents, causing incalculable losses.So how can we effectively avoid this phenomenon?So let's look at why this happens.

When laying electric wires, some people often pay no attention to the installation quality and do not install the casing where the insulation casing should be used.Instead of using the splice method, the wire joint USES the illegal hook - like connection method.The contact resistance of this hook type connection method is very large, and the constant heating when electrified will accelerate the aging of the cable insulation, leading to breakdown, and even make the nearby wood gradually dry, carbonization, and finally burn, causing a fire.

The cause of joint heating is known, then how to avoid the occurrence of this phenomenon, then Asian cable to share some tips for cable joint handling:

1. Conductor connection requires low resistance, so the cable is better to choose the anoxic copper like Asian cable. At the same time, pay attention to the different types of conductors such as copper and aluminum do not connect together, which will lead to oxidation and increase resistance.Connect the cable to have enough mechanical strength, the connection should not appear sharp Angle.

2. Where the cable has a shielding layer, make sure that the shielding layer is also connected inside and outside, and set aside part of the internal semiconductor shielding of the cable so that the shielding inside the connector head on the connection pipe can be connected with each other to ensure the continuity of the internal semiconductor, so as to make the field intensity at the joint joint evenly distributed.

3, cable reaction cone processing.

Construction shape, to the best of accurate to react cone, potential distribution on the cone is equal, in the production of crosslinking cable reaction cone, generally USES the special-purpose cutting tool, can also use a bit micro fire heating, use a sharp knife cutting, the basic shape, with a 2 mm thick glass scratch, in the end, from coarse to fine sand paper burnish, until smooth for until.

4, the role of metal shield is mainly used to conduct cable fault short-circuit current, as well as shield electromagnetic field electromagnetic interference, the metal shield in good grounding state is at zero potential, when the cable fault, it has the ability to conduct short-circuit current in a very short time.The grounding wire shall be solidly welded, and the metal shield and armor belt on the cable body of the box at both ends shall be solidly welded.

5. Sealing and mechanical protection of joints.

The sealing and mechanical protection of the joint is the guarantee to ensure the safe and reliable operation of the joint.Water and moisture should be prevented from infiltrating into the cable joint. Serious water seepage may lead to the scrapping of the whole cable. Therefore, the joint protection groove or cement protection box should be installed at the joint position.
