01 Definition of gold fittings
Power fittings, referred to as fittings, are connected and combined with various devices in the power system to transfer mechanical and electrical loads or play a protective role.
02 Basic Summary
The metal accessories of iron or aluminum widely used in power transmission lines are collectively referred to as fittings. Hardware is a wide range of different purposes, for example, to install wires with various wire clip, composition of insulator string hanging ring, connecting wires of various pressure over, tube, completing the split conductor on the various types of interval bar, etc., and with the tower with all kinds of wire, as well as related to the size of the conductor is used as a protection, must cooperate with each other.
Major gold provides need to bear bigger pull force in running, some assures electrical respect to contact is good even at the same time, it concerns the safety of conductor or tower, although one is damaged, also may cause line fault. Accordingly, the quality of fittings, correct use and installation, have certain influence to the safety of transmission line.
03 classification
1) According to the function and structure, it can be divided into hanging wire clip, tensioning wire clip, connecting metal clip, connecting metal clip, protection metal clip, equipment wire clip, T type wire clip, busbar metal clip, pull wire and other categories. (According to this classification, common line fittings are introduced below)
2) It can be used as wire fittings and transformer fittings according to the purpose.
3) According to the unit of electric power fittings, it can be divided into malleable cast iron, forging and pressing, aluminum, copper, aluminum and cast iron, altogether four units.
4) can also be divided into gb and NON GB, both we often say that the gold and non gold.
04 Suspension clip
Suspension clamp is a gold tool that suspends the lead (ground) wire to the suspension insulator string (group) or the gold tool string (group).
Suspensions are often shaped products, and now retain the u-bolt style of fixed suspensions (usually called boat clamp), which is composed of hanger U-bolts and hull. The other is the pre-stranded overhang clip.
Tension clamp
Tensioning wire clamp is the guide (ground) wire connected to tensioning string (group) or gold string (group) on the gold.
