The range is available in 7 ratings from 100 to 800 A. The standard IP 52 degree of protection makes KS suitable for the majority of locations. It can be increased to IP 54 by the addition of dust and damp proof blanking plates on the tap-off outlets. Tapping off is via tap-off units. These units, from 25 to 400 A, can be safely removed while live. 100 to 250 A trunking can take connectors and tap-off units up to 250 A. Higher rated trunking can take any tap-off unit from the range. Run components Straight distribution lengths Straight lengths are designed to carry current and feed loads with low or medium power. The straight lengths form the structure of the run. They comprise : 1 A casing of galvanised sheet steel, which is crimped closed. This casing, shaped and ribbed by rolling, provides excellent resistance to bending and twisting. Three casing widths cover the whole range. Casings are available in two finishes : - 54 mm wide galvanised sheet steel for 100, 160 and 250 A ratings (sheet steel with RAL 7032 grey finish available as an option) mm wide sheet steel with RAL 7032 grey finish for 400 and 500 A ratings mm wide sheet steel with RAL 7032 grey finish for 630 and 800 A ratings. 2 4 live conductors of the same cross-section : - Bimetal silver-plated copper/aluminium laminate for 100, 160 A ratings. - Aluminium fitted with bimetal silver-plated copper/aluminium laminate riders electrically welded to junctions and tapoff positions for 250 to 800 A ratings. The lamination is a patented process by which the copper and aluminium molecules are fused together under extreme pressure. 3 Fibreglass reinforced polyester isolators, at 250 mm intervals. These hold the conductors securely within the casing. 4 A special protected earth (PE) conductor of the same type as the live conductors with a cross-section 1/2 of the phase cross-section. It is connected to the casing at each junction. 5 Tap-off outlets on both sides of the trunking, at 1 m intervals. They are connected to the isolators to form a block, holding the bars. They have a shuttered outlet which is opened and closed automatically when connectors or tap-off units are plugged in or removed. 6 A mechanical and electrical jointing device. Electrical connection is via a block with spring and silver graphite contacts. This block absorbs the differential conductor/casing expansion of each length equally. For 100, 160 and 250 A ratings, it automatically and simultaneously connects all the live conductors, ensures continuity of the protective earth conductor and its connection with the casing. For higher ratings (315 to 800 A), the electrical connection is made by a 1/4 screw turn for each conductor /2 Te

The IP 52 degree of protection of Canalis KS means that it is suitable for installation in most industrial and commercial locations. For locations or sites which may be subject to water splashes in any direction the degree of protection should be raised to IP 54, by installing KSE-80YB2 sealed tap-off blanking plates (see page 11043/2). Changing levels in horizontal distribution KSA- LP42 KSE- YAi KSA- LP41 When trunking is mounted vertically, the degree of protection at a junction is IP 50. To maintain a degree of protection higher than IP 50, if required, each junction installed vertically must be fitted with a sealed jointing sleeve (IP 54). (See page 11043/2). Tap-off units n There are 2 ranges of tap-off units. i IP 40 protected range, low-cost and suitable for normal industrial and commercial environments. i IP 54 dust and damp proof range, for very dusty or damp environments.

It can also be used to tap off directly from the joint, between two lengths, for rising main distribution or low density distribution applications. This trunking has a compact design, namely with plated conductors inside a metal enclosure. The standard range is IP 52 (IP 54 as an option). The isolated conductor bars are made of nickel plated aluminium. The range is divided into 6 ratings from 200 to 800 A. The insulation used on the conductors is halogen-free 130 C class B polyester. The trunking has : - 4 conductors for the 3-pole + neutral version (crosssection of the neutral equal to the cross-section of the phases). Recommended for TNC scheme. The metal enclosure in prelacquered galvanised sheet steel (RAL 7032) provides protection and mechanical resistance for the conductors along their entire length. Moreover, the metal enclosure is used as a protective conductor (conforming to NF C15-100) with continuity ensured at each junction along the length of the installation. As an option, Canalis KVA can be fitted with an additional copper protective conductor (cross-section equal to half the cross-section of the phase).recommended for TNS scheme. With its compact design (no free space within the trunking), Canalis KVA can be mounted horizontally, edgewise or vertically without derating the rated current Ith. Moreover, this design does not require the mounting of a fire barrier joint to pass through floors and walls. Canalis KVA is designed to be fire-resistant for up to 2 hours. Run components ET Type These are designed to feed current through horizontal or vertical runs. A joint between two lengths can be replaced by a special joint which can be used as a tap-off point. These lengths are produced in fixed lengths of 4 metres or in 0.35 m to 2 metre lengths as required. EV Type These are designed for rising main distribution. The joint between two lengths can be used as a tap-off point. These lengths are produced in fixed lengths of 1, 2 and 3 metres or in 2.50 m to 4 metre lengths as required. They should be mounted with the neutral on the left. Junction block This is supplied with the ET run components and the components for changing direction. It provides an electrical and mechanical joint. When the run has a feed unit at both ends, an additional junction block must be ordered. 2 This is supplied with the EV run components. It can be ordered separately if ET components are used to replace the junction block and enable tap-off. It provides an electrical and mechanical joint as well as a tap-off point. The electrical junction is ensured by a single junction block (1 to 2 bolts per bar) which provides continuity for all the conductors. The bolt is made up of a screw and a contraction nut, the external head of which breaks when the tightening torque is reached. When the head of the nut breaks, a red washer is released, showing that the electrical junction operation has been completed successfully. For disassembly or maintenance operations, a second head is available. The recommended torque is thus 3 danm. The junction block contacts are silver-plated copper. 1/10 Te
