Sealing cap function: sealling the cable end

As an important part of the power system, the safety of the cable is very important to the stable operation of the whole power system. The sealing of the cable head by end cap is an important guarantee for the safety of the cable, and its importance cannot be ignored. In this paper, the importance of sealed cable head will be discussed in depth, aiming to improve people's understanding of cable seal and ensure the stable operation of power system.

Prevent the intrusion of moisture and impurities：

The tightness of the cable head can effectively prevent moisture and impurities from invading the interior of the cable. The intrusion of moisture and impurities will cause the cable insulation performance to decline, cause electrical failures, and even cause safety accidents in serious cases. The sealed cable end can effectively isolate the cable from the external environment, protect the insulation material inside the cable from damage, and extend the service life of the cable.

Prevent gas penetration：

During the operation of the cable, certain gases will be generated inside, and the existence of these gases may affect the performance of the cable. The sealed cable head can effectively prevent gas penetration and avoid the effect of gas on the cable performance, so as to ensure the stable operation of the power system.

Protection against electric field interference：

During the operation of the cable, a certain electric field will be generated. If the cable head is poorly sealed, the external electric field may interfere with the electric field inside the cable, affecting the normal operation of the cable. The sealed cable head can effectively prevent the interference of the external electric field to the internal electric field of the cable, and ensure the stable operation of the power system.

Sealed cable heads by end caps can effectively improve the safety of the power system. A poorly sealed cable head may cause electrical failure and may even cause a safety accident. The sealed cable head can effectively prevent the occurrence of electrical faults, improve the safety of the power system, and ensure the safety of people's lives and property.

Sealed cable head by end cap is an important measure to ensure the stable operation of power system. Only by fully recognizing the importance of sealing the cable head and taking effective measures to ensure the tightness of the cable head can we ensure the stable operation of the power system and provide reliable power guarantee for the economic development of society.
