70kN Porcelain Ceramic Disc Suspension Insulators for High Voltage
U70B U70CSuspension insulators are designed to link together into
strings, typically of two or more, to provide much higher voltage
protection than any single insulator. Suspension insulators are
typically used on high tension power transmission towers as shown
below. Porcelain is by far the most commonly used insulating
material but there are a number of glass styles as well. Porcelain
suspension insulators revolutionized the power distribution
industry allowing much higher voltage protection -- there are
several 1,000kV DC transmission lines utilizing suspension
insulators.Available for any voltage and contamination level by
