Ground Buss Insulator | High-Strength Fiberglass-Reinforced Design

ASK Tower Supply ground buss insulators are engineered for durability and precision, crafted from compression-molded, fiberglass-reinforced thermo-set polyester. This advanced bonded material offers superior moisture and heat resistance compared to plastic insulators, while delivering greater mechanical strength than porcelain. These qualities allow for tighter height tolerances, making them ideal for ground bar and perimeter grounding applications.

This product (ASK Pt.# 25225) is equivalent to Harger R4150S3 and matches the bus bar insulators found in all CommScope grounding kits, offering a reliable and cost-effective alternative.

Key Features:

• Material: Fiberglass-reinforced thermo-set polyester for enhanced strength and durability.
• Tapped Brass Inserts: 3/8"-16 brass inserts on both sides for secure connections.
• Thread Depth: 7/16" (11mm) on both sides.
• Dimensions:
  • Largest round body diameter: 1 3/4" (45mm), 16mm tall section.
  • Smallest round body diameter: 1.15" (29mm) (top and bottom).
  • Standoff height (total height): 1 1/2" (38mm).
• Electrical Performance: Can withstand up to 8kV rated for 1500V.
• Mechanical Strength: 2500-2700 lbf tensile strength.
• Operating Temperature: -40°C to 140°C (-40°F to 284°F).

Applications:

Designed for use in ground bar and perimeter grounding systems, this insulator's robust construction ensures reliable performance in demanding environments. Its high mechanical strength and tight tolerance compatibility make it a trusted choice for professional electrical installations.

For precision, strength, and reliability, this ground buss insulator is the ideal solution for your grounding needs, delivering performance equivalent to trusted industry standards like Harger R4150S3 and CommScope grounding kits.
