Distribution Insulators

Distribution insulators are engineered to mechanically support power lines while safely insulating any surrounding objects from conducting voltage.  Insulators maintain a non-conductive air gap that separates the conductor from a ground path and resists electrical, mechanical and even environmental stresses throughout the distribution system.


Peak Demand offers a complete line of high quality and proven distribution and sub-transmission level insulators.  The Pinnacle Series™ of porcelain insulators is a full line of pin and line post insulators manufactured using the wet process method to ensure the highest levels of quality and long term durability.  The Summit Series™ of composite silicone insulators include deadend and cutout insulators. The Duro Series™ of HDPE pin insulators utilizes high density polyethylene which is preferred by linemen and utilities both for its lighter weight, resistance to cracking and superior life expectancy.
