How To Choose Electrical Fittings

Hardware Powerfitting 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 protective functions. There are many power hardware, but how should we choose? The following article will give you an explanation. Iron or aluminum metal accessories widely used in power transmission lines are collectively referred to as hardware. There are many types of hardware, and their uses vary. For example, various wire clamps for installing conductors, various hanging rings that form green substrings, 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 tension during operation, and some must also ensure good electrical contact at the same time. It is related to the safety of the conductor or pole tower. 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 clamp. 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.
