Brown 381mm height 12.5kN Porcelain Post Insulators For Electric Power Distribution

Description:

Line post porcelain insulators shall conform in all respects to the requirements of ANSI standard. The insulators shall be made of good commercial-grade wet-process porcelain.The entire surface of the insulator, with the exception of a firing surface, shall be glazed. If gray is required, it shall be in accordance with ANSI Z55.1-1967 (R1973). Metal parts shall be made of a good commercial grade of malleable iron, ductile iron, steel, or aluminum. Ferrous parts, other than stainless steel, shall be galvanized in accordance with ASTM A153.

MAIN DIMENSIONS AND STANDARD PARTICULARS

1. Creepage distance 737mm

2. Cantilever strength 12.5kN

3. Low frequency flashover voltage

Dry 125kV

Wet 95kV

4. Critical impulse flashover voltage

Positive 200kV

Negtive 260kV

5. Radio influence voltage

Test voltage to ground 30kV

Applications:
Horizontal and gain-base line post insulators are often used in applications to avoid the need to install a cross-arm on the pole. ANSI 57-3S Line post insulators are designed to provide rigid support of conducting cable while offering the maximum resistance to damage from electrical or mechanical events.


Features:

Our porcelain insulators are manufactured using a wet porcelain process and cured in an environmentally controlled production facility to ensure a complete and even cure of the porcelain while also resulting in the highest quality surface finish.
