Pin Type Insulator

Porcelain Pin Insulators:

Voltage: 6kv-36kv

Parts: One piece or two parts assembled

Color: Brown,grey,white

Type: Porcelain thread type, zinc sleeve type


Porcelain pin insulators are used on distribution lines, normally used on 6kv, 11kv, 15kv, 22kv, 25kv, 33kv, 35kv.

Pin insulators are mounted on the poles or towers with spindle, the spindle has lead head type, steel head type and plastic head type. ANSI and IEC standard have different head dimension.

ANSI standard needs porcelain thread type pin insulators, assembled with lead head spindle.

IEC / BS standard need pin type insulators with zinc sleeve, assembled with steel head spindle.

The conductor is assembled on top or side of pin type insulators with preformed ties.

Standard: ANSI C29.5, ANSI C29.6, IEC 60383, BS3288


Important parameter: (if you want to enquire, the following must be provided)

Height (Can Have Bigger Tolerance) Creepage Distance Dry Arcing Distance Neck Diameter Puncture Voltage Cantilever Strength Porcelain Thread Type Or Zinc Sleeve Type With Semi-Conductor Glaze Or Not

If you provide code number, such as pin insulator 55-3, 55-4, 55-5, 56-1, 56-2, 56-3..., then only the code number is ok.
