Impact Tester

The ability of cable ducting and trunking systems for electrical installations to withstand impacts likely to be encountered during their working life is determined by dropping a guided weight from a pre-determined height over a cylindrical striker placed on the surface of the cable ducting and observing for signs of its failure under this impact.

The Globe Impact Tester for cable ducting and trunking systems consists of a guided cylindrical striker with its axis held along a vertical plane and a dropping weight which can be released from different pre-set heights to strike the top face of the striker. The striker, which rests on the surface of the cable ducting under test, is loosely guided by the lower end of a guide rod. The guide rod is firmly held inside a supporting block, which can be moved over two vertical rods for changing the dropping height.

Oil Bath

Test for resistance to oil for fittings for rigid non-metallic conduits is carried out by immersing the test specimen in insulation oil maintained at a temperature of 60 ± 1°C for a period of 48 hours. After this period, the fitting is taken out and kept at room temperature for 15 minutes. The fitting is than examined for the affect of oil.

 

The GLOBE Oil Bath for testing resistance to oil for fittings for rigid non-metallic conduits has double walled construction, with inner walls made of mild steel sheet and outer walls of CRCA sheet. The space between the two walls is filled with thermally insulating mineral wool. The top of the bath is made of stainless steel sheet and it is also provided with a stainless steel sheet lid. The oil in the bath is heated with the help of an electric heater and its temperature indicated and controlled by a digital temperature indicator-cum-controller. A motor-operated stirrer keeps the temperature uniform inside the bath. The equipment is complete with switch, fuse, indicators etc.

Collapse Tester

Collapse Tester For Rigid Non - Metallic Conduit

Non-metallic conduits used in electric wiring shall be sufficiently sturdy so as not to collapse when bent during laying. The ability of these conduits to bend without causing excessive deformation in their cross section or reduction in their cross-sectional area is determined by bending a portion of the conduit through an angle of 90°, maintaining it under bent condition for a period 24 hours inside a hot air oven maintained at a temperature of 60 ± 2°C, and subsequently passing a barrel shaped go-gauge through it. The gauge shall pass through the bent conduit under its own weight without any restriction.

 

This test is applicable to conduits of 16, 20, and 25 mm nominal sizes only.

 

The GLOBE Collapse Tester for electrical conduits consists of a jig for firmly holding a test specimen taken from the conduit under test in a bent state and a stand to mount the jig in a vertical plane such that a barrel shaped gauge can be passed through the conduit under its own weight under the effect of gravity.

Compression Tester For Rigid Non-Metallic Conduits

Conduits used in electrical installations shall possess adequate mechanical strength. One of the tests used for ascertaining the mechanical strength of conduits is the compression test. In this test, a test specimen taken from the sample of conduit under test is placed on a rigid flat surface and pressed from top with the help of a metallic cube. A specified load is applied on the conduit under test through the metallic cube and the reduction in diameter of the conduit determined. The load is then released and the recovery in the diameter is determined. The value of percentage deflection under load and percentage recovery after release of load are calculated and compared against specified values to evaluate the performance of the conduit under the action of compressive loads.

 

The Globe Compression Tester For Rigid Non-Metallic electrical conduits consists of a rigid platform for placing the test specimen on, an arrangement for compressing the conduit manually with the help of a hand-wheel and a screw arrangement, and a compression spring to apply the load on the conduit under test.

Bending Tester For Rigid Steel Conduits

Conduits used in electrical installations shall possess adequate mechanical strength. One of the tests used for ascertaining the mechanical strength of conduits is the bending test.

For rigid steel conduits, the test for bending is carried out by holding one end of a test specimen taken from the sample of conduits under test in a fixed holder and bending it over a grooved circular mandrel through an angle of 90°. During this operation, the test specimen is guided on its outer side by a grooved roller so that it follows the contour of the mandrel. The test specimen is then checked for effects of bending on it.

The GLOBE Bending Tester for Rigid Steel Conduits consists of an arrangement to mount grooved mandrels of specified sizes on a rigid platform and a pivoted lever to bend the test specimens against it through an angle of 90°.

 

The mandrel mounting arrangement has a central pivot pin about which semi-circular mandrels can be fitted with the help of allen bolts so that they are held rigidly. The mandrel for testing 16 mm diameter conduits is fixed permanently on the platform. Additional mandrels can be fitted over it to enable conduits of 20 and 25 mm diameter to be tested.

Bending Device For Flexible Non Metallic Corrugated

The flexible conduits are generally used for covering loose cables joining a fixed supply point to a fixed equipment or machinery. These may be made either from metallic or non-metallic materials. In either of the cases these conduits should be sufficiently flexible, so as to be able to bend to the specified radius without breaking. The ability of non-metallic flexible conduit to bend upto the desired degree is checked by bending it through four cycles of reverse bending through ninety degree over cylindrical mandrels having the specified radii. After that, the whole assembly is rotated by 45º and the specified gauge should be able to pass through the conduit under its own weight.

The GLOBE Bending Device for Flexible Non-Metallic Corrugated Conduits consists of an arrangement to fix two mandrels of specified radii fixed in a manner that there is a gap equal to the diameter of the conduit between them. A bush is provided to clamp the conduit under test. The arrangement is provided to ensure 90º bending around both the mandrel and to hold the conduit bent at 90º around one of the mandrel at the end of the bending operation. The whole assembly can be rotated by 45º manually, to facilitate passing of the appropriate gauge. (The gauge is not supplied with the equipment).

Heat Resistance Tester

Heat Resistance Tester For Pliable Electrical Conduits Of Insulating Materials

The ability of pliable electrical conduits made of insulating materials to withstand deformation at elevated temperatures is determined by keeping a 100 mm long piece of conduit under a specified load at a temperature of 60ºC for a period of 24 hours and determining the reduction in its cross sectional width because of the loading.

The GLOBE Heat Resistance Tester for pliable electrical conduits made of insulating materials consists of a metallic frame having a flat platform for placing a 100 mm long piece of conduit on, a horizontal metallic pin of 6 mm diameter held at the lower end of a vertical rod for applying the specified load on the conduit under test, and dead weights for applying the specified load on the conduit under test.

 

The loading rod is guided inside a vertical brass sleeve so that it can move only along a vertical axis. The weight of the loading assembly is 0.5 kg to enable testing of very light conduits. Additional weights of 0.5 kg and 1.0 kg are provided for testing light and medium conduits. These weights can be placed on a collar attached to the upper end of the loading rod.
