Station Post

MPS offers polymer Station Posts for line voltages class of 7.5 kV - 500 kV. These Station Posts are designed to ANSI C29.19 standards. These polymer Station Post meet the mechanical heights and comparable electrical performance of their equivalent porcelain TR numbers in ANSI C29.9, meaning they can be direct replacements for porcelain Station Posts in most cases.

Description

Features:
• 1/3 of the weight of a porcelain station post
• E Grade Epoxy Fiberglass Core
• Silicone housing for heightened electrical properties and resistance to contamination
• MPS’s Biaxial Compression Sealing System implemented on 69kv and Above

* For example, when replacing a TR 288 porcelain unit with a composite insulator, the given composite insulator deflection (2.6 inches) is measured at 560 lbs (40% of the TR 288's rated 1400 lbs) For Corona Ring, change catalog number to MA instead of MX
