Abstract
가스 배출관(12)에 연결되기에 적합하고 중합체 성분 및 미립 충전제로 이루어지는 전기적으로 비선형인 조성물로 제조된 전기적으로 비선형인 저항체(45)를 포함하는 원격통신 가스관 장치(40)이 기재되어 있다. 이 조성물은 25°C에서의 초기 저항률 ρi가 109ohm-cm 이상이며, 이 조성물을 함유하는 표준 장치는 초기 파괴 전압 Vsi를 가지고, 표준 충격 파괴 시험을 행한 후 0.7Vsi내지 1.3Vsi의 최종 파괴 전압 Vsf를 가진다. 또한, 이 장치내의 조성물은 25°C에서의 최종 저항률 ρf가 109ohm-cm 이상이다. 이러한 조성물은 가스 배출관(12)에 벤트-세이프 및 페일-세이프 보호를 모두 제공하는 데 유용하다.A telecommunication gas line device 40 is described that includes an electrically nonlinear resistor 45 suitable for being connected to the gas discharge line 12 and made of an electrically nonlinear composition consisting of a polymer component and particulate filler. The composition has an initial resistivity ρ i at 25 ° C. of at least 10 9 ohm-cm, and the standard device containing the composition has an initial breakdown voltage V si , and 0.7 V si to 1.3 V after a standard impact break test. has a final breakdown voltage V sf of si . In addition, the composition in this device has a final resistivity ρ f at 25 ° C. of at least 10 9 ohm-cm. Such a composition is useful for providing both vent-safe and fail-safe protection to the gas outlet 12.
