Description

Technical Field

[0001] The utility model relates to the technical field of composite lightning arrester jackets, in particular to a composite lightning arrester jacket which is convenient to install. Background Art

[0002] Lightning arrester is an electrical appliance used to protect electrical equipment from high transient overvoltage hazards during lightning strikes, and to limit the follow-on time and often the follow-on amplitude. The arrester is connected between the cable and the ground, usually in parallel with the protected equipment. Lightning arresters can effectively protect communication equipment. Once abnormal voltage appears, the arrester will take action and play a protective role. When the communication cable or equipment is operating at normal operating voltage, the arrester will not take effect and will be regarded as a short circuit to the ground. Once high voltage appears and endangers the insulation of the protected equipment, the arrester will immediately act to direct the high voltage impact current to the ground, thereby limiting the voltage amplitude and protecting the insulation of the communication cable and equipment. When the overvoltage disappears, the arrester quickly returns to its original state, allowing the communication line to operate normally.

[0003] There are many kinds of lightning arresters, including metal oxide arresters, line-type metal oxide arresters, gapless line-type metal oxide arresters, fully insulated composite jacket metal oxide arresters, detachable arresters, etc. Lightning arresters are set outdoors for a long time and need maintenance or replacement after aging.
