What Are The Common Causes of Nylon Cable Failure And How To Analyze Them

According to XSD understanding, the most direct cause of nylon cable failure is due to the degradation of the insulation layer and lead to breakdown, there are many factors that reduce the conductive insulation, according to our experience in the industry for more than ten years of practical operation out, so you can summarize the following situations, take a look at it.

1, the external damage of nylon cable

There are many factors that lead to external damage to photovoltaic cables, such as: unqualified cable laying and installation structure and alignment too chaotic and many other factors can lead to mechanical damage, and also easily affect the normal operation of underground cables, such as civil and industrial buildings in the cable damage. Sometimes, if the degree of damage is not serious, it may take months or even years to make the damaged parts completely damaged, and sometimes even serious short-circuit failure may occur, which directly affects the safety of electrical equipment production.

2, the cable insulation is affected by moisture

Substandard nylon cable joints and joints in wet weather, joints in the long time under the action of the electric field will produce water or water vapor. Ground water and trees mixed together, insulation strength gradually lead to cable damage.

3, photovoltaic cable long-term overload operation

Due to current overload operation, the thermal effect of the load current through the wire and cable will inevitably lead to conductor heating. At the same time, the skin effect and charge eddy current loss, steel armor electrical loss will also generate additional heat in the cable, thus increasing the cable temperature, and eventually lead to PV cable failure, such as the first time can not be dealt with is required to hurry to stop the operation, to avoid more serious accidents.

4, the cable connection failure

Photovoltaic wire joints are the weakest link caused by cable personnel often occurring cable joint failure and direct negligence. In the construction workers of the cable joint manufacturing method, if the crimp is not tight and inadequate heating, it will reduce the insulation of the cable head and may lead to accidents.

Well, the above is the introduction of "what are the common causes of nylon cable failure, how to analyze", hope it can help you! We recommend to continue to pay attention to XSD Cable, to learn more information.
