Porcelain line post insulator formation:

Porcelain line post insulator consists of and metal accessories with cement gel pack, insulation and support in the overhead power line wires and line post insulator are normally used for under 132 kv line, like pin insulator, as on a line support wires, one end of the connection wire, one end is installed on the cross arm, unlike pin insulator, insulator line column is the breakdown type.

Porcelain line post insulator classifies:

Colligation type and clamp type insulator at the top is divided into two kinds. Porcelain insulator's head can be divided into binding porcelain insulator and clipping wire type of porcelain insulator. Wire clip type for the porcelain of the head of the binding for vertical and horizontal installation clip accessories. Porcelain of binding site using sand structure, to ensure that the mechanical strength, prevent loose and reverse.

Porcelain line post insulator cantilever strength:

To the type of connecting with the conductor, line post insulator can be tie top design or clamp top design. To the mounting direction, it can be horizontal or vertical. The cantilever strength can be 5KN, 10KN, 12.5KN, 16KN.
