1 Busbar Trunking Assembly 00A-600A : 000V Horizontal and Vertical applications Suitable for Reliable Power Distribution to: > industry > highrise buildings - transformer to switchboards - switchboards to loads upto 600A, 000V BTA busway meets all low-voltage electrical distribution needs...

2 Medium Power Transmission High Power Transmission and Distribution Compact, with a casing which favours thermal exchanges, characterized by its low impedance and voltage drop, BTA trunking is particularly suited to long runs. Its aesthetic styling enables it to be fully integrated into industrial and commercial buildings, sports facilities and many other premises of modern design. BTA Trunking allows : Transmission of electrical power by way of horizontal or vertical installations in the industrial and tertiary sectors and residential buildings, in which IP 5/54 minimum degree of protection is required. - Transformer-panel, panel-panel, generator or any other type of power link. - High power distribution through a range of 5 to A tap-off boxes. - Distribution in risers for office or residential multistory buildings. General Features This trunking is of compact design and incorporates fully anchored busbars. The prelacquered steel plate casing favours thermal exchange. It is low-impedance trunking allowing power transmission over long distances. BTA copper or aluminium conductors are insulated throughout their length by Class B (0 C) polyester films. Aluminium conductors comprise a bi-metal section at junctions and tap-offs. As a result of its anchored busbar design (there is no gap between busbar and casing) a fire barrier element is not required. BTA trunking can be installed vertically, horizontally, flatwise or edgewise without downgrading its strength. 0

3 High Power Transmission and Distribution A The Technology : BTA trunking complies with the IEC Standard Degree of protection is IP 5 or IP 54. umber of live conductors = or 4. Rated voltage = 000 V. Ratings available from : 000 to 00 A, with copper conductors, 800 to 4000 A, with aluminium conductors. The fully enclosed casing comprises four 6/0 gauge prelacquered galvanized/phopshatized sheet steel sections (RAL 70/5 colour). The straight units are, or metres long and incorporate P + PE or P + + PE conduction configurations. The casing comprises the protective earth conductor, electrical continuity is reliably ensured at the junctions. Optionally, BTA units can be provided with a specific protective earth conductor located inside the casing. Electrical connection between units is provided by a "junction block" tightened by one to four prevailing nuts, which simultaneously ensures splicing of the live conductors as well as of the protective earth conductor. Possible maintenance operations are undertaken using a torque spanner (tightening torque = 6 da m). Mechanical connection between two units is provided by two junction covers assembled using eight captive screws. Various accessories are offered for feeding, covering the ends and changing the direction of the trunking. Two types of trunking OBTA trunking without tap-off windows providing power transmission links. OBTA trunking with tap-off windows which can receive the following tap-off boxes : 5 to 400 A plug-in boxes, incorporating spring-clip connectors, which provide frictionally tight tap-offs, 400 to A boxes, tightened using a prevailing torque bolt, which provide mechanically fixed tap-offs; these boxes can only be connected/disconnected when power is off. Remark Copper conductors are recommended for cases involving severe usage of BTA trunking with tap-off windows and plug-in tap-off boxes (e.g. welding plant supply systems). 0
