Line Surge (LSA)

Line surge arresters are crucial for maintaining the integrity and safety of electrical systems by protecting them from voltage spikes and surges. Our ProtectaLite line surge arresters are designed to safeguard transmission and distribution lines by protecting the air around an insulator during lightning events. These devices prevent insulator flashovers, which would otherwise require a circuit breaker or reclose operation to clear the fault. By safely diverting the lightning surge to the ground, ProtectaLite arresters ensure the continuous operation and reliability of the electrical network. Available in custom designs to accommodate system voltages ranging from 2.4 kV to 765 kV, they are ideal for a wide range of applications, from residential to industrial settings. Investing in these arresters enhances safety, reduces maintenance costs, and prolongs the lifespan of electrical devices
