CSA Standards

This part of IEC 71 constitutes an application guide and deals with the selection of insulation levels of equipment or installations for three-phase electrical systems. Its aim is to give guidance for the determination of the rated withstand voltages for ranges I and II of IEC 71-1 and to justify the association of these rated […]

The chopped-impulse test is often specified to represent the severe condition of stress within the apparatus (particularly in winding structures) produced by collapse of the voltage when a line or bus insulator flashes over near the apparatus. This test is a lightning-impulse test with the tail of the impulse chopped after the crest at some

This Standard specifies requirements for covered overhead distribution line wire. These conductors are intended for overhead installation as single conductors on single-phase or three-phase electrical distribution systems.

This Standard defines the measurement technique for determining the efficiency of HID and LPS lamp ballasts for use in HID and LPS luminaires that are to be installed in industrial, commercial, or residential locations.

These specifications apply to impregnated paper- insulated,metallic-sheathed cable of the “solid” type which is to be used for the transmission. and distribution of electrical energy on electric utlity systems.

This Standard specifies requirements for concentric-lay aluminum stranded conductors, with or without a central core of reinforcing steel strand. These conductors are intended for overhead installation on single-phase or three-phase electrical distribution systems.

This Standard covers the electrical and mechanical characteristics of aluminum 1 350 wire, in annealed and intermediate tempers, for stranding into conductors or for use as solid single conductors.

This Standard covers the electrical and mechanical characteristics of (a) round 1350-H19 hard-drawn aluminum wires (A1) before compacting; (b) round zinc-coated hard-drawn steel core wires (S1A); and (C) bare compact round concentric-lay-stranded aluminum conductors steel reinforced, constructed from the wires specified in Items (a) and (b) and intended for use in overhead lines.
