A channel comprising an elongate slot for receiving a length of a flexible conduit. The slot comprises an opening extending along its length for laying a flexible conduit into the slot and for removing the flexible conduit therefrom and a barrier which is biased to block at least part of the opening in the absence of an externally applied force.

An arrangement for providing a charging connection for an electric vehicle, the arrangement comprising: an elongate groove formed in a surface of a pavement or sidewalk; and a conduit received within the elongate groove, the conduit having an open state and a closed state, wherein in the open state the conduit defines an opening at the surface of the pavement or sidewalk, through which at least a portion of a vehicle charging cable may be inserted into the conduit, and in the closed state an exposed surface of the conduit at the surface of the pavement or sidewalk covers the vehicle charging cable.

The present disclosure provides an underground cable enclosure having a body made of a composite material, and a cover assembly having at least one cover rail that is made of polymer cement and molded to at least a portion of the body, and at least one cover that is made of polymer cement and can rest on the at least one cover rail.

A separation duct for encompassing an elongate member. The duct includes longitudinal internal spacers extend longitudinally in a direction of a longitudinal axis of the duct. A longitudinal plane for each spacer is substantially parallel to the longitudinal plane of the other spacers. The spacers support the elongate member and resist slippage of the duct relative to the elongate member. The duct may be used to provide separation and protection for elongate members of a range of outside dimensions.

A process for extruding a divided conduit comprising obtaining an extrusion die head, inserting a strip-shaped substrate into the extrusion die head such that the strip shaped substrate is located within the tip gap and extends at least partially out of the tip gap such that the longitudinal edges are located in the die gap, and flowing molten polymer through die gap, encapsulating the longitudinal edges of the strip-shaped substrate in molten polymer. The extrusion die head contains a tip region and a bushing. The tip region contains at least 2 tips separated by a tip gap. The bushing extends around the tip region and the distance between the tip region and the inner surface of the bushing is defined to be the die gap and the die gap varies around the bushing.

A method of producing a divided conduit containing, in order forming a strip-shaped textile having a first longitudinal edge and a second longitudinal edge, extruding a molten thermoplastic polymer into the form of an at least partially molten conduit having an inner surface and an outer surface, and placing at least one strip-shaped substrate within the at least partially molten conduit during or directly after conduit formation such that the first longitudinal and second longitudinal edges of the strip-shaped substrate embed into the inner surface of the conduit. The strip-shaped textile is selected from the group consisting of a woven, non-woven, and knit and the strip-shaped textile is air permeable. The inner surface and outer surface of the conduit is continuous.

A divided conduit containing a thermoplastic conduit and at least one strip-shaped film having a first longitudinal edge and a second longitudinal edge which are embedded into the inner surface of the conduit forming at least two flexible, longitudinal channels for enveloping cables or other elongated structures.

A method of forming a conduit having at least one strip-shaped fabric substrate dividing the conduit into channels. The method contains obtaining an extrusion die configured to form the wall of the conduit and a slot configured for receipt of a strip-shaped fabric substrate and introducing a strip-shaped fabric substrate into the slot. The strip-shaped textile is air permeable and contains enlarged regions at the first and second longitudinal edges. Molten polymer is introduced at a first point in the extrusion die and at the first point the slot and the area configured to form the wall of the conduit are not in communication. The slot is exposed to the molten polymer at a point between the first point and the die exit forming the first polymeric layer of the conduit such that the first longitudinal and second longitudinal edges of the strip-shaped fabric substrate embed into the molten polymer.

The invention relates to a modular and compact arrangement (200) of three phases (A, B, C) of a gas-insulated apparatus (100), that is suitable for placement inside a tunnel or a pipe (106) or another confined space. According to the invention, the three phases (A, B, C) are arranged in a triangle or side-by-side on a fixation part (103, 104) which includes a roller system (105; 105a, 105b, 105c, 105d). This allows the insertion of such a three-phase assembly (100) into confined spaces such as pipes or tunnels (106), without the need for access by workers or machinery. Furthermore, the present disclosure relates to a method for assembling and installing such a three-phase arrangement (100) into the confined space (106).

A cable protection system is provided that includes mating features for enabling efficient and effective assembly around a cable to be protected.
