8-Card Shelf Configurations
Single 8-card Shelf HVI Cabinet
The Teleline Isolator 8-card Shelf HVI Cabinet Assembly, Model 751950/15 provides a safe working environment for all personnel, while protecting the telecommunications network from hazardous voltages and currents.
Single 8-card Shelf HVI Backboard, with Dual NIU Housings
The Teleline Isolator 8-card Shelf HVI Backboard Assembly, Model 751950/05CU6 provides a safe, reliable, cost effective solution for isolating wireline communication circuits entering sites susceptible to high-voltage influences due to Ground Potential Rise (GPR) caused by lightning and/or power faults.
The Teleline Isolator offers 70kV peak, 50kVrms protection on each communication circuit, while permitting continuous communications before, during, and after a GPR event.
Single 8-card Shelf HVI Backboard
The Teleline Isolator 8-card Shelf HVI Backboard Assembly, Model 751950/05 provides a safe, reliable, cost effective solution for isolating wireline communication circuits entering sites susceptible to high-voltage influences due to Ground Potential Rise (GPR) caused by lightning and/or power faults.
The Teleline Isolator offers 70kV peak, 50kVrms protection on each communication circuit, while permitting continuous communications before, during, and after a GPR event.
Features
