Overview

Standard Reference: HD 604 S1:1994 (adopted nationally as SIST HD 604 S1:1998)
Title: 0,6/1 kV and 1,9/3,3 kV power cables with special fire performance for use in power stations
Organization: CLC

HD 604 S1:1994 defines requirements for rigid and flexible conductor power cables for fixed installations with rated voltages 0.6/1 kV and 1.9/3.3 kV, specifically where cable insulation and sheaths are intended for use in power stations and substations. A core focus of the standard is on special fire performance, ensuring cables maintain critical functionality and reduce fire propagation and harmful emissions in generation and distribution facilities.

Key Topics

The standard addresses technical and safety elements including:

• Voltage classes covered: 0.6/1 kV and 1.9/3.3 kV for fixed installations.
• Conductor types: rigid and flexible constructions suitable for plant wiring and equipment connections.
• Insulation and sheath materials intended for the power station environment, with emphasis on fire behaviour.
• Fire performance requirements covering ignition resistance, burning behaviour and reduced contribution to fire development (general performance categories; specific test methods are defined in the full text).
• Marking, documentation and identification to support safe installation and maintenance in power generating plants.
• Scope limitations: applies to fixed installation cables used in power plants and substations rather than general-purpose building cables.

Applications

HD 604 S1 is practical for organizations involved in the specification, procurement, manufacture, testing and installation of power cables in high-consequence electrical environments:

• Power plant and substation designers specifying cables for turbines, switchgear rooms and control circuits.
• Cable manufacturers developing products with enhanced fire performance for the energy sector.
• Procurement and compliance teams ensuring purchased cables meet required safety and operational criteria.
• Testing laboratories and safety engineers verifying fire performance and documentation for installed systems.
• Facilities maintenance teams selecting replacement or upgrade cables where fire resilience is critical.
