Built For Reliability

MPS guy strain insulators are designed with the highest quality materials and manufactured using one piece flow techniques making sure each unit is manufactured to specification. Additionally, all end fittings are crimped to ensure a secure and consistent connection with 100% factory tensile testing to ANSI C29.11 national standards for quality validation. 

Advanced Coatings

MPS offers a full line of silicone coated guy strain insulators in ratings of 15,000, 21,000, 30,000, 36,000 (Guy Strain Insulator PIB) 50,000, and 80,000 lb designs. The silicone coating offers improved UV protection and contamination performance characteristics. MPS's extruded HTV (high temperature vulcanized) silicone rubber formulation has been lab-tested and field-proven since 1984, is completely bonded to the fiberglass rod during production, won't tear away or fall off over time, eliminates potential voids to prevent moisture ingress, and provides the same insulating protection and hydrophobicity performance as MPS's high voltage transmission insulators.
