Steatite Heavy Duty Standoff Insulators

Applications and Properties of Steatite Heavy Duty Standoff Insulators

When heavy loads and high voltages are present in stationary applications, LSP Heavy Duty Standoffs are required. They provide an effective means of supporting large electrical components such as busbars or capacitors. Only a few of the more popular sizes are shown in this catalog. When hostile environments are present, convolutions or petticoats can be provided on the glazed surface of the insulator. White glaze is standard on ail exposed ceramic parts, with brown glaze available optionally. Permanent marking under the glaze may also be used.

CAPS

Metal end caps used to provide attachment to your devices are available plated or unplated in brass, aluminum, or galvanized iron and are permanently cemented to the ceramic insulator. Threaded holes in any configuration can be produced.

BASES

Two base styles are used for Heavy Duty Standoffs-Style 1 is an elliptical shape while Style 2 is round. Style 2 bases are used on large diameter standoffs to support heavy loads. Materials are the same as for the caps.

ACCESSORIES

When high peak voltages are present, corona shields may be used on the top cap. These are available for most standoff sizes. Cable clamps may also be requested for the top cap.
