Full title and description

STB BS EN 50180-2:2015 — Bushings above 1 kV up to 52 kV and from 250 A to 3,15 kA for liquid filled transformers - Part 2: Requirement for bushing components. This is the British (BS) adoption of the European Standard EN 50180-2:2015 and specifies requirements for individual bushing components used on liquid‑filled power transformers within the stated voltage and current range.

Abstract

This standard defines component-level requirements for bushings intended for use with oil‑insulated (liquid‑filled) transformers with highest voltages above 1 kV up to 52 kV and rated currents from 250 A up to 3,150 A. Part 2 complements the general and dimensional requirements given in EN 50180 (Part 1) by addressing the characteristics, materials, dimensions, interfaces and tests applicable specifically to bushing components to ensure safety, interchangeability and reliable operation.

Scope

Specifies requirements for components of ceramic or resin insulated bushings for liquid-filled transformers having highest voltages above 1 kV up to 52 kV and rated currents from 250 A to 3,150 A (frequencies typically 15 Hz to 60 Hz). The standard covers the dimensions, material characteristics, mechanical and electrical interfaces, marking and documentation necessary to ensure safe performance, interchangeability and compatibility of bushing components with mating connectors and transformer mounting arrangements.

Key topics and requirements

• Voltage and current rating limits and intended application (liquid‑filled transformers, 1 kV–52 kV, 250 A–3 150 A).
• Materials and construction requirements for bushing components (ceramic, resin, metal parts, seals).
• Dimensional details and tolerances to ensure interchangeability with mating parts and plug‑in connectors.
• Mechanical strength and mounting/interface requirements (threads, flanges, fixings).
• Electrical requirements including insulation coordination, creepage/clearance and leakage paths.
• Type and routine tests, checking procedures and acceptance criteria for components.
• Marking, labelling and documentation requirements for traceability and correct installation.
• Compatibility guidance with Parts 1 and 3 of the EN 50180 series and references to related electrical standards.

Typical use and users

Primary users include transformer and bushing manufacturers, design and R&D engineers, utilities and power network operators, procurement/specification teams, conformity assessment and testing laboratories, and maintenance/operations personnel responsible for selection, installation and replacement of transformer bushings and their components.

FAQ

Q: What is this standard?

A: BS EN 50180-2:2015 is the British adoption of the European standard EN 50180-2:2015, titled "Bushings above 1 kV up to 52 kV and from 250 A to 3,15 kA for liquid filled transformers — Part 2: Requirement for bushing components." It sets requirements for individual bushing components used on liquid‑filled power transformers within the stated ratings.

Q: What does it cover?

A: It covers component-level requirements — materials, dimensions, mechanical and electrical interfaces, tests, marking and documentation — to ensure safety, reliability and interchangeability of bushing components for liquid‑filled transformers rated 1 kV–52 kV and 250 A–3,150 A.

Q: Who typically uses it?

A: Transformer and bushing manufacturers, utilities and network owners, design engineers, test laboratories, procurement teams and maintenance personnel use this standard for design, specification, testing and acceptance of bushing components.

Q: Is it current or superseded?

A: The document was published in 2015 and is listed as the 2015 edition (published 31 October 2015 for the BS adoption). National catalogues list it as the current/confirmed version; users should verify local national-body status and any later amendments or revisions before relying on it for procurement or compliance.

Q: Is it part of a series?

A: Yes — EN 50180 is a multi-part series. Part 1 covers general requirements for bushings, Part 2 covers bushing components (this document), and Part 3 covers requirements for bushing fixations. There may be amendments/corrigenda to individual parts.

Q: What are the key keywords?

A: Bushings, transformer bushings, liquid‑filled transformers, bushing components, interchangeability, insulation, dimensions, mounting, EN 50180-2, BS EN 50180-2:2015.
