ขาย BELLCOMMS 000792SANKOSHA Gas Tube Arrestors are designed with surge limiting voltage

SANKOSHA Gas Tube Arrestors are designed with surge limiting voltage characteristics within a defined level. Circuits, equipment, and personnel are protected from abnormally high transient voltage cause by lightning, accidental contact with power lines, or electromagnetic induction by the spark - over that occurs in the gas chamber at the given voltage. Type 3YVH Ceramic arrestors consist of three electrodes and an opening in the center electrode allows the two gaps of the arrester to share a common gas chamber. When a spark - over occurs in one end of the arrestors an almost simulataneous spark - over occurs in the other end. This simulataneous discharge minimizes the current surge in the protected lines. ELECTRICAL CHARACTERISTICS 3YVH - 230AF5 1. DC spark-over voltage 100V/s 220 V ± 20% 2. Impulse spark-over voltage 1kV/μs ≤ 650 V 3. Insulation resistance 100 V.DC ≥ 100GΩ 4. Capacitance 1MHz ≤ 5 pF 5. DC Holdover voltage * ITU – T K.12 / Test 3 135 V ≤ 150 ms 6. Impulse Life 10 / 1000 μs, 10 KA x 2 300 times 7. Impulse discharge current 8/20μs, 10 KA x 2 10 times 8. AC discharge current 50Hz 1 sec 5 times ** After test of item 6, 7 and 8 1. DC Spark – Over Voltage 100 V / s 2. Impluse Spark – Over Voltage 1 kV / μs 220 V ± 20% ≤ 650 V 3. Insulation Resistance 100 V. DC ≥ 100 GΩ * Test method shall complied with CCITT K. 12
