MACRO DUCT INTEGRITY TEST APPARATUS (DIT)
Duct Integrity Test apparatus can be convienently used for carrying of various tests like duct alignment , air tightness test, shuttle test and also useful for cleaning the before installations of O F C in Plb/ silicore ducts of various diameter 32mm,40mm and 50mm with safe environment. Can also be used for blowing / pulling ropes inside the duct , floating the fiber for small distance range @ 300 meters air blown fiber
1. Duct Testing
Duct cleaning, sponge deformation test to ensure no sharpened objects or sharp cuts inside the laid plb/ silicore ducts( which will protect Fiber from damages while installing the O F Cable Into plb ducts).
2. Pressure Test
Pressure test ensures the coupling joints of push fit orthreaded grip couplers , their leak proof thus ensures smooth blowing of Fibercables while doing air jet blowing Fiber installations.
3. Duct straightness Test
This test carried by passing a wooden or plastic shuttle piece of suitable diameters ( which will varies according to duct sizes) intoplb / silicone ducts by means of DIT apparatus and ensure that underground ducts where laid as per permissible tolerance so that OFC can be laid under safely.
4. Rope Blowing.
Nylon , poly propelene or plastic ropes can be easily blown into ducts for their short distance OFC pulling by manual methods or atemergency circumstances and also blow rope into standby unused ducts for their future usage.
