A cable guide (110 figure 2b) comprises an upper face (120) and a lower face (130). The lower face (130) has a generally convex form so as to lie in contact with the flow channel 101 when fitted in the flow channel 101. The upper face (120) has a generally concave form and is shaped to minimise disturbance of the flow when fitted in the flow channel 101. A passage is defined between the lower face (130) and the flow channel having an entrance opening (113) at a first end 111 of the cable guide (110) and exit openings 114 on the sides of the cable guide towards a second end 112. By utilising a cable guide (110), disruption to the flow within the channel 101 by the entrance or exit of the cable is minimised. Additionally, the guide (110) restricts the lateral movement of the cable prior to entering opening (113), preventing the cable lying across the direction of flow. The cable guide is suitable for use in the flow channel of a sewer. |
