Porcelain Insulator Mechanical Cantilever and Tension Test Machine

Large horizontal hydraulic tension machine that loads pin and suspension porcelain insulators to rated failing load and to destruction. Used by high voltage insulator manufacturers and electrical utility laboratories.

Specification

The insulator is clamped at both ends and loaded in tension to its rated mechanical failing load. Load is held for 60 seconds, then raised to failure, with a digital display and safety guarding.

Features

• Hydraulic ram with servo valve
• Horizontal base frame
• End fittings for different insulators
• Peak load hold
• Safety covers on both sides
