REQUEST CALLBACK
This test is to determine the ability of the cable to withstand a sudden snatch load. A cable sample of 4.5 meters length is taken for test.   The sample is terminated in a manner that the fibres, sheathing and any strength member/members are clamped together firmly at both ends.  

The prepared cable is held horizontally and firmly clamped at the two ends slightly less than 4.5 Meter apart so that a sag of 300 mm., is formed in the centre with a tensile load of 300 N in the cable.   The attenuation is then measured. A hook formed from a round shaft of diameter of 25 mm is held over the cable
sag such that the initial distance between the cable and the hook is 100 mm.  The hook has a mass attached to give total falling weight of 30 Kg.  The radius of impacting surface of the crown of the hook shall be 12.5 mm.    

 

The hook with the mass attached, is then released so as to catch the cable after dropping from the height of 100.   There will be 10 successive drops.  After these drops, the load is removed and there shall be no permanent physical damage to the cable and the change in attenuation of the fibre after the test shall be ≤ 0.05 dB both 1310nm and 1550 nm wave length.

The purpose of the test is to wind multiple turns of the OFC on a step drum of diameters of 150 mm, 200 mm, 300 mm and 400 mm. The appropriate step diameter is chosen for the cable under test to ensure that the drum diameter is just under 20 times cable dia. The test is typically composed of multiple cycles of winding “m” complete turns on a drum in clockwise direction followed by complete unwinding, where typically m = 4. This cycle is repeated “n” times, where typically n = 10.

 

The operator presses SET to set the No. of winding turns on the drum in each cycle. The value is selected by pressing ‘>’ and ‘^’ keys and selected by pressing ENT. The same procedure is then repeated to program the No. of Cycles “n” of winding and unwinding. Pressing RUN will start the automatic test. The machine automatically stops at end of program. Pressing STOP can stop the test midway. Pressing PAUSE can pause the test, which can resume by pressing Start again.

This machine is for testing the optical fibre cables to the specifications listed in IEC-60794-1-E4. The machine is designed for dropping weights of up to 5 Kgf on cables from heights of up to 1 Meter. Typical tests can be 10 impacts of 25 N-M (2.5 KgM) delivered by weight of 50 N (5 Kgf) falling over 0.5 M Height. However this height can be adjusted between 100 mm to 1 M depending on the client requirement. The basic hammer weight is 1 Kg and additional hammer weights can be selected of a combination of 0.5 Kg ( 2 supplied) and 1 Kg ( 3 supplied) to make a total of up to 5 Kg of hammer. The falling weight falls on an intermediate plate or thimble with a bottom radius of 12.5 mm. The thimble is located correctly over the centre of the cable and is guided by a spider mounted on the base of the table.

 

The test is performed automatically by programming the number of cycles over which the weight has to fall on the left thumbwheel switch.  The time for descent of the pneumatic cylinder is set as ON time and rise is set as OFF time on the respective thumbwheel switches.  "

 

"Press ‘SET’ to set the SL.ON TIME i.e. impact time. Using ‘>’ ‘^’ keys program the set value and Press “ENT’. Repeat the procedure to program SL.OFF TIME i.e. impact off time and CYCLES of impact test. Press ‘RUN’ to start the test. The test will automatically stop after completing the set Cycles. Press ‘STOP’ to terminate the test in between. Press ‘PAUSE to pause the test ‘’START’ to resume. Display can be scrolled up using ‘^’ key to read the elapsed impact on/off times cycles

Pneumatic Cylinder - 25 bore, 1030 mm stroke, 10 Bar, Rod 16 mm dia.

This machine is for testing optical fibre cables to the specifications listed in ( IEC 60794-1-2-E1A) / (EIA -455-33A) with a minimum sample length under test of 150/200 M with 6/8 cable falls under simultaneous and equal tension. The machine has two stands kept app. 25 M apart. One stand has fixed return sheaves for the cable and the other stand has the mounting drums for clamping the cable and a movable trolley with pulleys to apply tension to the end-clamped cable.

The machine is supplied with a PLC based controller which allows its operation in manual / auto modes. The main drive motor is an AC motor with V/F drive and servo controller.

 

The machine can export data to any connected PC which when loaded with the supplied software by us can show the progress of the test and plot the strain (displacement of the sheave), tension (load in the load cells), and tensile strength (derived from strain and tension) data of load versus time as a trending graph, and also allow printout of the same..

The machine is a static workbench consisting of a 3 Metre long corrugated plastic tray supported over a metal frame of suitable length and working height. The plastic tray can support up to 4 OFC cables laid parallel over alternate flutes. A hydraulic manifold is mounted on the machine at one end of the plastic tray with pipe nipples in front of each of the OFC cable end positions. The manifold also connects to a drain, an overhead water tank of adjustable height and an incoming feeding pipe.

This is Abrasion tester of cable sheath and cable sheath markings ( IEC 60794-1-21 Method E2A and E2B, respectively) .

The cable sheaths of OFC cables can be PE, PVC, LSZH HFPO.


Requirement of test E2A is to determine whether the outer sheath withstands repeated abrasions. The requirement of test E2B is to determine whether
the printing on the OFC cable sheath is rubbed off by abrasion.

 

For both test, the cable has to be held horizontal and a hard ground pin of 1 mm diameter is rubbed against the cable sheath. Therefore the rubbing is caused by a curved surface of 0.5mm radius. The pin is held at lower end of a vertically floating load, which can be varied between 1 to 10 Kgf.


The rubbing stroke is adjustable between 2 – 20 mm and oscillating frequency is adjustable between 5 - 100 strokes per minute. Total number of strokes can be set up to 9999. The operator presses SET on the control panel to set the Abrasion stroke count. The keys ‘>’ and ‘^’ on the panel allow to enter the appropriate value and pressing ENT selects the value. Pressing of RUN starts the test which automatically stops on completing of the SET cycles. Pressing “Pause” pauses the cycle and “Start” restores the cycle operations. The display shows the current cycle count.
