What is BS 2562 – cable boxes for transformers and reactors about? 
BS 2562 is a British Standard that specifies requirements for cable boxes in which the cores of cables terminate within the box and are connected to the fixed terminals.
The boxes are intended for the termination of impregnated-paper-insulated solid-type lead or aluminium sheathed cables having copper or aluminium conductors and for the termination of extruded insulated and sheathed unarmoured cables having copper or aluminium conductors.
The boxes are suitable for operating indoors or outdoors under conditions of ambient temperature, loading, altitude, etc., envisaged by BS 171.
Note: BS 2562 does not apply to boxes where the cable cores pass through to the transformer without a joint or are joined to cable tails in the box by sleeves or thimbles.
Who is BS 2562 – cable boxes for transformers and reactors for?
BS 2562 on ‘cable boxes for transformers and reactors’ is useful for: 
- Manufacturers and suppliers of cable boxes and cables
- Manufacturers and suppliers of transformers and reactors
- Suppliers of electricity / power companies

Why should you use BS 2562 – cable boxes for transformers and reactors?
The standard box discussed in BS 2562 is arranged for cables approaching vertically from below and is not bi-directional. Where cables approach vertically from above, alternative parts are required. BS 2562 provides you with details of the range of boxes with the help of tables.
BS 2562 specifies standard envelope dimensions and fixing dimensions of cable boxes to achieve interchangeability whatever type of filling medium is to be used, and also to specify dimensions of components, e.g., bushings, glands, for interchangeability of such parts.
The boxes discussed in BS 2562 are suitable for rated voltages up to 36 kV and currents up to 2500 A.
BS 2562 provides you with design principles, general considerations, and tests for a range of cable boxes up to and including 36 kV rated voltage. BS 2562 also specifies the essential dimensions and component details for the range of cable boxes. BS 2562 also specifies wiping glands for metallic sheathed cables. In addition, BS 2562 lists the information to be given with enquiry and order.
BS 2562 guidelines help you to follow best practices when designing and manufacturing cable boxes for transformers and reactors. This contributes to the safe supply of power to users.
