How To Choose Electrical Fittings

Pole mounted fuse switch, is a metal accessory that connects and combines various devices in the power system, plays a role in transmitting mechanical loads, electrical loads and some kind of protection. There are many power hardware, but how should we choose? The following article will give you an explanation. The iron or aluminum metal accessories widely used in power transmission lines are collectively called hardware. There are many types of hardware, and their uses are different. For example, various wire clamps for installing conductors, various hanging rings for forming green sub-strings, various crimping tubes and repair tubes for connecting conductors, various types of spacers on split conductors, etc. In addition, there are various types of wire pulling hardware for poles and towers, and the size of the wires used for protection must be matched with each other. Most hardware needs to withstand large pulling forces during operation, and some must also ensure good electrical contact at the same time. It is related to the safety of conductors or poles. Even if a ring is damaged, it may cause line failure. Therefore, the quality, correct use and installation of hardware have a certain impact on the safe power transmission of the line. According to the main performance and use of hardware, hardware can be roughly divided into the following categories: 1), Suspension hardware, also known as support hardware or suspension wire clamps. This kind of hardware is mainly used to hang the conductor on the insulator string (mostly used for straight pole towers) and to hang jumpers on the insulator string. 2) Anchor hardware, also known as fastening hardware or wire clamp. This kind of hardware is mainly used to fasten the terminal of the conductor to fix it on the wire insulator string. It is also used to fix the terminal of the lightning arrester and the anchor hardware of the pull wire. It bears all the tension of the conductor and lightning arrester. Some anchor hardware becomes a conductor.
