72~144 Core 2 in 2 out Horizontal Type IP67 fosc Fiber Optic In line Splice Closure With Air Valve
Introduction
optical splice closures are used to distribute,splice,and store the outdoor optical cables which enter and exit fromthe ends of the closure.There are two connection ways:directconnectionand splitting connection. They are applicable to situations such as overhead, man-well of pipeline, embedded situation etc .Comparing with terminal box , the closure requires much stricter requirement of seal.Sealing ring and air valve are required for closure,but that are not necessaryfor terminal box
Main technical Indexes:
Seal performance :the pressure in the closure is 100Kpa,put the closure into the water for 15 minutes, there is no air bubble,and observed it for 24 hours,there is no change of air pressure
Re-entryperformance:after3 times of normal operations,it can still be up to the seal performancestandard
Insulation resistance: ≥2×104MΩ
Withstand voltage strength :there is no puncture and no arc-cover after the function of 15KVDC/1min
