Overview
IEC 60189-2:2007 is the International Electrotechnical Commission standard that specifies requirements for low‑frequency cables and wires with PVC insulation and PVC sheath - specifically cables in pairs, triples, quads and quintuples for inside installations. It applies to cables intended for interconnection of transmission equipment, telecommunications equipment and data‑processing equipment in indoor environments. The standard addresses construction, materials, dimensions, mechanical, thermal and electrical requirements and includes normative annexes for colour coding, unit identification and screened variations.
Key topics and technical requirements
The standard defines practical, testable requirements for indoor PVC‑insulated, PVC‑sheathed low‑frequency multi‑element cables. Major technical topics include:
Applications
IEC 60189‑2 is aimed at indoor cabling used for:
- Telecommunication links inside buildings and equipment rooms
- Interconnections between transmission and data‑processing equipment
- Internal cabling for PBX and digital exchanges (see annex on screened pairs)
Keywords: IEC 60189-2, PVC insulated cables, inside installations, low-frequency cables, pairs triples quads quintuples, telecommunication cable standards.
Who should use this standard
- Cable manufacturers and designers specifying PVC‑insulated low‑frequency multi‑element cables
- Procurement and specification engineers for telecom and data centres
- Test laboratories and conformity assessors performing mechanical, thermal and electrical testing
- Installers and integrators ensuring compliance with indoor cable requirements
