ETF 3 Cable-friendly burning ETF 3 Cable-friendly burning for pilot and tele-communication cables ■■ Direct control of the burning process by life monitoring ■■ Highly cable-friendly burn process ■■ Specially adapted to the requirements of telecom and pilot cables ■■ Capable of locating humidity faults DESCRIPTION The ETF (Energy Separation Filter) 3 kV was specially developed to perform fault location on symmetrical communication and pilot cables. The combination of a burn unit, ETF 3 and Teleflex allows an operator to quickly perform fault prelocation on high resistive and humid cable faults. Where many other measuring technologies fail, the ETF 3 even allows humid faults to be prelocated safely. The ETF 3 provides a solution for applications where the permitted voltage is limited – by cable type or allowed test voltage level – to a level that prevents the use of the standard burn and fault location technology. The burn procedure can be directly observed on the display of the connected Teleflex. The moment the fault breaks down, the fault distance becomes visible. This permits a “cable-friendly” limitation of the burn time to the required duration. For safety reasons, the input of the ETF 3 voltage is automatically limited to 3 kV by an internal arc gap because the ETF 3 and any connected communication and pilot cables have limited permittable voltage levels. Exceeding these permitted values will have far reaching negative consequences. Using the ETF 3 requires the utmost caution and observation of these values. Combinations are available in the following variations (in order of performance): Reflectometer with burn unit Analogue Teleflex T 22/13 B 5 kV mode Teleflex MX BT 500 IS-1 Teleflex T 30E MMG 10 in 1 kV mode Teleflex SX works with all burn units Telefelx VX works with all burn units TECHNICAL DATA* ETF 3 Maximum burn voltage Maximum burn current Dimensions Weight 3 kV 10 A 360 x 180 x 220 mm approx. 15 kg ORDERING INFORMATION Product Order no.
