Product Definition
An insulator that is used in distribution networks that works with low voltage is known as a shackle insulator. This insulator is also known as a spool insulator. These insulators can be worked in two positions like horizontal otherwise vertical. At present, the usage of this insulator has decreased because of the underground cable used in distribution purposes.
In the transmission line, the pole must bear the transverse (horizontal) tension of long straight section of wire. In order to bear this transverse tension, the construction party often uses tension insulators. In low-voltage lines (below 11kv), spool insulators are often used as tension insulators. However, for high voltage transmission lines, pin or disc insulator strings are required to be connected to the cross arm in the horizontal direction. When the tension load in the line is very high, such as at a long span, two or more insulator strings need to be used in parallel.
Based on the good insulation performance of ceramics, spool insulators are often made of high-quality ceramics. The spool insulator is designed to meet the power demand in the most economical and effective way. In addition, the porcelain spool insulator can withstand high temperature and current, which is the best solution for the maintenance and safety of various electrical equipment.
Products Use
The insulator’s tapered hole distributes the load more consistently & also reduces the possibility of fracture once loaded heavily. The shackle insulator includes a conductor within the groove and it is fixed by using a soft binding wire. The shackle type insulator diagram is shown below.
D-iron fittings with shackle insulator or spool insulator
The applications of this insulator include the following.
It is used in a distribution system by arranging in between tower & conductors to support & insulate.
These insulators are used in overhead lines with low & medium voltage.
This insulator is used with a bolt by placing on the pole otherwise telegraph to avoid outflow current from conductors
It can be used in both positions like horizontal & vertical position.
