NEMA - C29.14B

Composite Insulators Guy Insulator Type (Uncoated or Painted Type)

active, Most Current
Organization: NEMA
Publication Date: 1 January 2021
Status: active
Page Count: 16
scope:

This Standard covers composite guy (strain)-type insulators made of a fiberglass-reinforced resin matrix core rod and metal end fittings intended for use on overhead distribution lines for electric power systems to insulate or isolate guy wires for corrosion protection, increased insulation levels, or clearance for maintenance and normal operation. The fiberglass-reinforced core rod may be painted or veiled for additional weather protection.

Strain-type insulators with polymer coatings are covered in NEMA C29.14A.
