GPJ117-3B optic cable closures use the switch-on mechanical-pressure-sealed system and are widely applied to communication cable connections.

Characteristics:
1) The shell uses high-grade engineering plastic. The external constructions and fasteners are made of stainless steel;
2) Applied to the connection and distribution of buried, suspended and conduit optical cables;
3) Have great intensity and good air/waterproof ability, and be accommodated to unfavorable conditions;
4) Overlaid coiling fibers;
5) Reliable cable fixation;
6) Easy to operate and use; Has stable performance.

Technical parameters:
1) Internal pressure: Constant at 0.5Pa (waterproof)
2) Pressure resistance: 200MPa (20-meter depth into water)
3) Insulation resistance high-voltage protection and inner shell: 5,000m??/500V DC
4) Voltage resistance between box HV protection and inner shell: 15,000V?? (DC)
5) Optic cable tensile: 1,000N
