What is BS 5067 - Flameproof transformers used in mines about?
BS 5067 is a British standard that specifies design requirements for dry-type flameproof three-phase power transformers intended for use below ground in mines.
BS 5067 does not apply to transformers of the types covered by BS 2538 and BS 5126-4. Transformers comply with BS 171 for the rating and performance of the main component within the flameproof enclosure, except where specifically modified or extended in BS 5067.
Who is BS 5067 - Flameproof transformers used in mines for?
BS 5067 on flameproof transformers used in mines is useful for:
- The mining industry
- The electrical industry
- Electrical equipment manufacturers
- Mechanical engineers
- Quality assurance managers
Why should you use BS 5067 - Flameproof transformers used in mines?
These transformers lessen the risk of fire and explosions underground by suppressing arc explosions with non-explosive nitrogen gas. To avoid moisture penetration, the tank is hermetically sealed and positively pressurised, providing the unit with a substantially longer working life.
BS 5067 provides its users with guidelines for insulation, voltage adjustment tappings, design and construction, and overvoltage protection and earthing.
Using BS 5067 guidelines ensures electrical safety, protection from overvoltage, quality assurance, and durability for longer service life.
