LT Polymer Pin Insulator – Safe and Efficient Insulation for Low Voltage Networks
A LT Polymer Pin Insulator (Low Tension Pin Insulator) is a key component of low voltage (LT) overhead power distribution. Built for strength, safety, and efficiency, the LT Polymer pin insulator is an essential component, which provides support and electrical insulation for the LT conductors, on distribution poles, used at a maximum voltage of 1.1 kV.
Due to polymer composite materials and advanced feature designs, polymer L.T. pin insulators outperform traditional ceramic or porcelain insulator types on durability, weather protection, and handling. Because of these benefits, polymer LT insulators are used broadly by power utilities, contractors and infrastructure developers for new and maintenance projects.
