SIST HD 626 S1:1998

Overhead distribution cables of rated voltage Uo/U(Um): 0,6/1 (1,2) kV

HD 626 applies to cables of rated voltage Uo/U(Um) = 0,6/(1,2) kV used in overhead power distribution systems mainly for public distribution, of maximum system voltage not exceeding 1,2 kV. This part (Part 1) specifies the general requirements applicable to these cables, unless otherwise specified in the particular sections of this HD. Test methods are specified in HD 383, HD 405, EN 60811 and in HD 605 or in Part 2 of this HD. The particular types of cables are specified in Parts 3 to 8.

Overview

HD 626 S1:1996 (CLC) specifies the general requirements for overhead distribution cables with rated voltage Uo/U(Um) = 0,6/1 (1,2) kV used in overhead power distribution systems-primarily public distribution networks with maximum system voltage not exceeding 1,2 kV. This is Part 1 of the HD 626 series and sets the baseline requirements applicable unless a particular Part (Parts 3–8) states otherwise. Test methods are referenced to established documents (HD 383, HD 405, EN 60811, HD 605 and/or Part 2).

Key topics and requirements

HD 626 S1:1996 addresses the following technical areas (general requirements scope):

• Scope and ratings: applicability to overhead distribution cables rated 0,6/1 (1,2) kV and maximum system voltage limits.
• Construction and materials: baseline expectations for cable construction and acceptable materials (conductors, insulation, sheath or protective layers) as applicable to overhead use.
• Electrical performance: requirements related to rated voltage behavior and fundamental electrical properties for safe distribution use.
• Mechanical and environmental performance: expectations for mechanical strength, weather resistance and suitability for overhead installation conditions.
• Dimensions, marking and documentation: general provisions for conductor sizes, overall dimensions, identification/marking and manufacturer documentation.
• Quality and conformity: requirements for compliance, inspection and routine tests via referenced standards.
• Test methods: test procedures are not re-stated in full but are specified to be carried out according to HD 383, HD 405, EN 60811, HD 605 or Part 2 of HD 626.

Note: HD 626 S1 provides general rules; specific cable types and detailed parameters are defined in subsequent Parts (3–8).

Practical applications

HD 626 S1:1996 is used by:

• Cable manufacturers to design and certify overhead distribution conductors for 0.6/1 (1.2) kV systems.
• Power utilities and distribution network operators specifying cable purchases and ensuring network compatibility and safety.
• Consulting engineers and system designers selecting appropriate overhead distribution cables for public distribution projects.
• Procurement teams and specifiers creating technical tender documents.
• Testing laboratories and conformity assessors applying the referenced test methods to verify compliance.

Typical use cases include replacement or new installation of overhead lines for local distribution, specification of insulated aerial cables, and compliance checks during factory or site acceptance testing.
