Abstract: A cable gland sealing member comprising: a sleeve (19) arranged to be slidably received within a passage (9) defined in a body (5) of a cable gland, the sleeve (19) arranged to receive a settable sealing material for forming a seal to a cable passing through the sleeve, wherein the sleeve (19) is defined by an annular side wall extending along an axial length; wherein an outer surface (71) of the sleeve (19) includes a tapered portion (95) such that the external diameter of the sleeve (19) widens in the tapered portion (95); and wherein the outer surface (71) of the sleeve (19) is arranged to form a seal with the cable gland body (5). A cable gland is also disclosed using such a sealing member.

Abstract: A modular lighting fixture includes a modular housing portion and one or more separate modular lighting components arranged adjacent to the modular housing portion. The separate modular lighting component(s) can include a lighting assembly having a plurality of LED devices and a plurality of optics. Each optic is secured relative to one of the plurality of LED devices. The lighting fixture also includes at least one securement assembly that secures the modular housing portion and the modular lighting component(s) together. More specifically, the securement assembly may include at least one end plate that secures the modular housing portion and the separate modular lighting component(s) together.

Abstract: A battery assembly for a lighting fixture is provided. The battery assembly includes a battery unit comprising a battery unit housing and a first set of conductive pins. The battery unit housing is configured to accommodate one or more batteries configured to power one or more light sources of the lighting fixture. The first set of conductive pins are in electrical communication with the batteries. The battery assembly includes a battery interface comprising a battery interface housing and a second set of conductive pins. The battery interface housing is configured to accommodate the battery unit housing. The second set of conductive pins are coupled to the light source(s) so that the batteries power the light source(s) when the first set of conductive pins contact the second set of conductive pins. In some implementations, the battery unit can be inserted into the battery interface while the lighting fixture is energized.

Abstract: A driver assembly (200) for a lighting fixture (100) is provided. The driver assembly (200) includes a housing (220) defining a cavity (234). The driver assembly (200) includes a driver circuit (210) disposed within the cavity (234). The driver circuit (210) can be configured to provide power to one or more light emitting diodes (116) of the lighting fixture (100). The driver assembly (200) can include a potting material (237) disposed within the cavity (234). The driver assembly (200) can include a base (260) attached to the housing (220) to enclose the driver circuit (210) and the potting material (237) within the cavity (234).

Abstract: A gland assembly includes a gland body (3) and a cap nut (5) connected by screw threads (25). A cable holding device (11) is received within the cap nut (5) and has a plurality of fingers (19) configured to apply a gripping force to a cable (7) extending through the gland assembly in response to a torque applied to the cap nut (5). The fingers (19) are configured to increase the gripping force on the cable (7) in response to a linear force applied to the elongate member.

Abstract: An electrical switch including a jaw assembly, a housing and a blade assembly. The jaw assembly is electrically connected to a first electrical conductor. The housing assembly is electrically connected to a second electrical conductor. The blade assembly is fixedly attached to said housing assembly at a first end thereof and having an electrically conductive blade contact fixedly attached to a second end distal from said first end. The housing assembly and said blade assembly pivot about a first axis to drive said blade contact into said jaw assembly to close said switch. The blade assembly is operable to rotate about a second axis perpendicular to said first axis only when said distal end of said blade assembly is seated in said jaw assembly.

Abstract: A diaphragm seal (101) for a cable gland (FIG. 1) has concentric inner (103) and outer (105) cylindrical seal walls connected at one end by a diaphragm (107) to define a cavity (121). The cavity (121) contains a plurality of support webs (125) that extend between the inner (103) and outer (105) seal walls. The webs (125) are provided on an exit side of the seal (101) and deform to assist insertion of the cable through the seal (101) from an entry side of the seal (101). The webs (12) resist inversion of the seal (101) when the pressure on the exit side is higher than the pressure on the entry side to create a pressure differential across the diaphragm (107).

Abstract: A cable gland for a cable includes a body, an insert located within the body, the insert having an internal axial bore, and an adaptor provided with positive location structure arranged in use within the bore of the insert.

Abstract: A method and apparatus for characterising a three phase transformer (3) using a single phase power supply (1). Pairs of input terminals (H0-H3) of the transformer are sequentially energised for each energisation and the voltage between pairs of output terminals (x0-x3) of the transformer are measured. Measured voltages are processed in order to characterise the winding configuration of the transformer. Either simultaneously or subsequently the presence of neutrals on the primary and/or secondary side of the transformer are identified to enable the winding configuration to be further characterised. Subsequently any phase displacement of the transformer is determined.
