Do you know the damage that an aging cable brings

According to fire department statistics, more than 60% of fires are caused by electrical line failures every year. Cause serious casualties and property damage. The aging and quality problems of wires and cables have become the main causes of fire accidents. So what are the reasons for the aging of cables and wires?

external force injury

Judging from the operation analysis in recent years, especially in areas with rapid economic development, many cable failures are caused by mechanical external force damage. Sometimes, if the damage is not serious, it may take months or even years for the damaged area to completely break down and cause failure. Sometimes short-circuit faults may occur if the damage is serious, directly affecting the safe production of electricity and power-consuming units.

Insulation gets damp

Generally occurs at cable joints directly buried or in pipes. For example, if the cable joints are not made up to standard and the joints are made in humid climate conditions, water will enter the joints or water vapor will be mixed in. This will gradually destroy the insulation strength and cause accidents.

Chemical corrosion

Corrosion in cables is often caused by long-term exposure to chemicals or electrical corrosion. Corrosion of the outer sheath or corrosion-resistant protective layer causes cable failure.

Long-term overload operation

Overload operation will cause the temperature of the cable to rise due to the thermal effect of the current. During long-term overload operation, excessive temperature will accelerate the aging of the insulation and even cause breakdown of the insulation.

Cable connector failure

Cable joints are the weakest link in cable lines. The failures caused by direct personnel negligence (poor construction) often occur. During the process of making cable joints, if the construction workers find that the joints are not tightly crimped or heated insufficiently, the insulation of the cable head will be reduced, thus causing an accident.

Wire aging is really a huge problem in our daily life and production. Then how to deal with that? In fact, the solution is very simple and you just need a hose protector. Here I recommend you spiral hose guard and fiberglass fire sleeve. They can protect your cable from heat, fire, aging, wear and impact. Then the cable can serve much longer. Besides, there will not be aging and fire problem.
