We in the heat shrink cable accessories construction more or less because of the small carelessness, improper practices will lead to a series of adverse consequences.

So in the construction we need to pay attention to is that the heat shrinkable cable accessories connected to the tight connection, crimp contact resistance is too large, in the operation will lead to overheating.

Heat-shrinkable cable accessories three-phase pressure connector geometric position asymmetry, will produce asymmetric electric field, thus accelerating the degree of insulation aging.

It should be noted that the insulation filler and heat shrink tubing in the production will produce residual bubbles, the role of the electric field will occur under the partial discharge, and ultimately lead to insulation breakdown.

The most important small details, heat shrink cable accessories in the production process, crimp crimping after the metal burr if the treatment is not clean, the process will produce cutting-edge discharge, and ultimately lead to insulation through the discharge.

So, we should pay attention to the construction of small details and techniques of the problem, in order to avoid the above will occur the adverse consequences.
