This British Standard specifies requirements for various types of
insulation, voltage categories and dimensions for a standard range of
insulated flexible cables and flexible cords (commonly known as “coil
end leads”), that are intended to be connected directly and permanently
to a coil winding or other component of electrical apparatus.
The types of cable specified in this standard are as follows:
Type 4 cable, voltage categories A, C, D, E and F, for a designated
temperature of 90 °C (flame retardant, rubber insulated coil leads);
Type 5 cable, voltage categories A, C, D, E and F, for a designated
temperature of 180 °C (180 °C silicone rubber insulated coil leads).
NOTE A guide to the use of the cables specified in this British Standard is
given in Annex A. A summary of the tests applicable to the cables is given in
Annex B.
