Our polymer long rod insulators combine the highest levels of electrical insulation and mechanical tensile strength in a compact, lightweight design. According to long-established Siemens tradition, every production step is rigorously monitored and controlled. All Long Rod Insulators are designed and tested in compliance with the latest norms and standards.Thanks to their superior design and low weight, our long rod insulators are especially suitable for overhead compact-line applications. They are also more economical to transport and install, and make it possible to build more space-saving electricity poles.
