Full title and description

DIN VDE 0250-813 (VDE 0250-813):1985-05 — Cables, wires and flexible cords for power installation; trailing cable (German: Isolierte Starkstromleitungen; Leitungstrosse). This national German standard defines designation, constructional and testing requirements for trailing power cables intended for use as flexible supply leads in industrial and mobile applications.

Abstract

This standard specifies the essential characteristics and minimum requirements for trailing cables (Leitungstrosse) used in power installations: conductor construction, insulation and sheath materials, mechanical strength and flexibility requirements, marking and basic type testing. It is a concise technical specification (short national part within the VDE 0250 series) intended to ensure safe, reliable performance under the mechanical and electrical stresses typical of trailing operation.

Scope

DIN VDE 0250-813 covers trailing cables used as flexible power-supply leads where cables are subject to frequent movement, abrasion and mechanical stress (for example on mobile machinery, excavators, cranes and other material-handling equipment). The standard sets out requirements for conductor type and class, insulation and sheath materials (typical rubber types), mechanical reinforcement and testing to ensure safe continuous operation in trailing applications. It focuses on constructional and performance criteria rather than installation rules.

Key topics and requirements

• Designation and intended application: trailing cable (Leitungstrosse) for power installation.
• Conductor construction: flexible stranded copper conductors, defined classes for flexibility.
• Insulation and inner layers: specified insulating rubber/elastic materials and semiconductive layers where required.
• Sheath and mechanical protection: abrasion-, oil- and ozone-resistant rubber sheaths; tear-resistant inner tapes or reinforcements for trailing operation.
• Electrical characteristics: rated voltage classes and basic electrical tests appropriate to the cable type.
• Mechanical tests: flexing/abrasion/tensile tests to verify suitability for trailing use.
• Marking and documentation: type identification, rated voltage, manufacturer and date/lot marking as required for traceability.

These topics reflect the construction, testing and marking focus typical of VDE/DIN product standards for mobile and flexible power cables.

Typical use and users

Typical users and applications include cable and cable-assembly manufacturers, electrical designers and specifiers for industrial installations, maintenance engineers, mining and material-handling operations (open-cast mining, mobile heavy equipment), and test laboratories assessing cable suitability for trailing applications. The standard is referenced when selecting or specifying flexible trailing power cables that must withstand repeated movement and harsh mechanical conditions.

Related standards

DIN VDE 0250-813 is part of the broader DIN VDE 0250 family (cables, wires and flexible cords for power installation). It partially replaces earlier national parts in the 1975 series and should be considered alongside other cable standards and later series (e.g., related VDE/DIN parts dealing with insulation types, conductor classes and cable testing). Users often consult adjacent VDE 0250 parts and product-specific standards for higher voltage classes or special environments.

FAQ

Q: What is this standard?

A: DIN VDE 0250-813:1985-05 is a German VDE/DIN standard specifying requirements for trailing cables (Leitungstrosse) used as flexible power-supply leads in industrial and mobile applications.

Q: What does it cover?

A: It covers designation, conductor construction, insulation and sheath materials, mechanical reinforcement, basic electrical and mechanical tests, and marking relevant to trailing cable types. It addresses construction and performance rather than installation practice.

Q: Who typically uses it?

A: Cable manufacturers, electrical specifiers, maintenance and procurement engineers in heavy industry, mining and material-handling sectors, and test laboratories use this standard when designing, specifying or testing flexible trailing power cables.

Q: Is it current or superseded?

A: The VDE/DIN listings show DIN VDE 0250-813:1985-05 as a published national part; VDE catalogues list it as a valid document. Users should verify the current applicability when specifying cables (national standards can be amended or superseded); check with the official standards body or VDE for the latest status before use.

Q: Is it part of a series?

A: Yes — it belongs to the DIN/VDE 0250 series (cables, wires and flexible cords for power installation) and should be considered together with other parts of VDE 0250 that cover different cable types, voltages and special conditions.

Q: What are the key keywords?

A: Trailing cable, Leitungstrosse, flexible power cable, rubber-insulated, abrasion-resistant sheath, VDE 0250-813.
