SIST HD 603 S1:1998

Overview

HD 603 S1:1994 (CLC) is the Part 1, general-requirements specification for distribution cables of rated voltage 0.6/1 kV used in underground power distribution systems, mainly for public distribution networks. This HD defines the scope and general provisions applicable to these low-voltage distribution cables (nominal voltage not exceeding 0.6/1 kV AC). It establishes baseline requirements that apply unless a specific provision is given in the particular Parts (Parts 3–8) that define individual cable types.

Key topics and requirements

HD 603 S1:1994 focuses on the essential, non-type-specific requirements for 0.6/1 kV distribution cables. Main topics include:

• Scope and definitions relevant to underground low-voltage distribution cables (rated voltage 0.6/1 kV).
• General construction principles covering conductor, insulation, bedding and sheath concepts as they pertain to distribution cable design.
• Electrical and mechanical requirements such as rated voltage, performance under normal and fault conditions, and mechanical durability for underground installation.
• Marking, documentation and identification requirements for cables supplied to utilities and contractors.
• Quality and conformity aspects that manufacturers and purchasers should meet before acceptance.
• Reference to test procedures - HD 603 S1:1994 delegates specific test methods to other standards (see Related Standards). It sets requirements while relying on those referenced documents for test execution and verification.

(HD 603 S1:1994 provides general requirements only; detailed properties for particular cable types are given in Parts 3–8.)

Applications and users

This standard is practical and relevant for:

• Cable manufacturers designing and documenting 0.6/1 kV underground distribution cables.
• Power utilities and distribution network owners specifying cable performance and procurement criteria for public underground distribution.
• Consulting and design engineers preparing specifications, designs, and installation details for low-voltage distribution networks.
• Testing laboratories and quality inspectors using the general requirements in conjunction with referenced test standards to verify compliance.
• Procurement managers and regulators ensuring products meet accepted CLC/HD requirements for public distribution systems.

Using HD 603 S1 helps ensure consistent safety, interoperability and reliable performance of underground distribution cables rated 0.6/1 kV.
