Kontaktledning/Legerte materialer og diverse deler


These specifications apply to the production and delivery of alloy materials and miscellaneous parts for overhead contact line systems to Bane NOR SF (hereinafter referred to as BN in this document) in connection with the conclusions of one or more framework agreement(s). Scope of delivery is defined in this documents 🔗 Appendix.

Requirements given in this document must be followed when purchasing «alloy materials and miscellaneous parts» for overhead contact line systems belonging to BN.


In this chapter the requirements to the relevant components are defined in three main sections:

  • General requirements
  • Technical requirements
  • Requirements to documentation/tests

If some of general and technical requirements or requirements for documentation and testing is increase the cost compared with the tenders evaluation/assessment of the requirements utility, we request special response on this in accordance with the tender documentation.

2.3.4 Additional requirements for delivery

Technical specifications for overhead contact line material are divided according to the material of the components. Some components in connection with a technical specification shall nevertheless be delivered as a complete composite component consisting of several sub-components with different materials. It appears from the description of F.nr. and drawing no. in point for 🔗 scope of delivery when such composite components are to be delivered.

If a sub-component consisting of material other than the relevant technical specification is mainly to be delivered, as part of a composite component, this sub-component shall be delivered in accordance with requirements given in the detailed drawing for the sub-component where such a detailed drawing exists. Any detailed drawing for a component of material other than the relevant technical specification shall be enclosed in the technical specification for the relevant material.

Some components shall be delivered both as part of a composite component and as a separate sub-component. What is to be delivered is stated in items in the list for 🔗 scope of delivery.

2.3.5 Documents The following documents shall be kept with the supplier and delivered at BN's request:

4.1 Remarks to the scope of delivery

The drawings listed in the scope of delivery include parts that are mandatory in BN's modern overhead contact line systems as well as parts in older overhead contact line systems that are ordered on demand. Some of these parts may also be supplier dependent and as such deviate from the attached drawing(s). Hence the scope of delivery is marked as follows:

M = Mandatory
R = On requirement
* = Supplier dependent

This marking can occur either solely or in combination.

One or more of the drawings referred to here, in the technical specification and scope of delivery for «Alloy materials and miscellaneous parts» are supplier dependent, other suppliers can offer their own products that have similar function, performance, construction and service life. Such products shall be approved specifically by BN. In connection with the introduction of new components, where there are no satisfactory production drawings, the supplier shall send a technical documentation of the component for approval. Documentation for approval shall include drawing in file format (pdf.files) and/or open data models (IFC.files), technical data, test reports, etc. Some components shall undergo a test period before final approval is given. Test procedures and requirements for results are determined by BN.
