◇ Overview and Features shear pin signal is used for hydropower turbine guide vane shear pin hole. When the shear pin is cut when an electrical signal. Where: CJX type is normally closed; KJX type is normally open. Normally closed shear pin signal is required and ZJX-3A-type shear pin signal devices supporting, normally open no trim shear pin signal devices. ◇ Technical parameters 1) Voltage <220V; 2) resistance <0.2Ω; 3) the use of current <1A; 4) Ambient temperature: 0 ~ 45 ℃; 5) Humidity <80%; type B diameter diameter length L C CJX-9 9 22 60 KJX-9 CJX-14 14 25 80 KJX-14 CJX-18 18 25 100 KJX-18 CJX-20 20 25 100 KJX-20 CJX-25 25 25 100 KJX-25 CJX-30 30 35 100 KJX-30
