We have been known and acknowledged as a reliable and dependable testing machine manufacturer that brings out a huge range of several testing equipment like Electric Conduit Testing Equipment. The main objective of conduits are that these are used in electrical installations shall possess adequate for mechanical strength. These are also suitable for ascertaining the mechanical strength of conduits on various parameters and compressive loads. Our range include several general and safety requirements for household and similar electrical appliances with these conduits. These equipments are in confirmation to various specification like:
IS 6946 – 1973, IS 9537, IS 366 – 1991, IS 3854 – 1997, IS 6290 – 1986 and many more.
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 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 GLOBECollapse 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.

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 GlobeCompression 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.
