Test

CENELEC HD 629.1

Describtion

Application
The heat-shrinkable termination MONOi is used for indoor installation on polymeric insulated single core medium voltage cables with extruded easy strip conductive screen or bonded extruded conductive screen. It is suitable for copper wire or copper tape screened cables.

With this high quality system termination, the entire range of cross-sections is covered with just a few sizes per voltage level. The conductor can be alternatively connected with mechanical or compression cable lugs. The termination is available with additional splitting accessories for three-core cables.

Technical characteristics
The one-piece, co-extruded (dual wall) insulation body GT12 consists of an inner stress control tube and an outer anti-tracking layer. It can be shrank on the prepared cable in at least one shrinking procedure and is characterized by a very low construction length.

Electrically strained areas (e.g. the screen cut) are covered with stress control mastic providing additional stress relief supporting the steadily safe operation of the termination. Sealing mastic (MBA) in the area of cable lug and copper wire screen prevents a possible penetration of humidity.

Specifications and standards
The termination meets the requirements of CENELEC HD 629.1 S2 and IEC 60502-4.

Technical instructions and application information (accessories)

The data given were determined diligently, but do not release our customers of the duty to carry out tests themselves in order to check the suitability of the products delivered by us for the intended use. We reserve the right to modify characteristic and performance data according to the present state of technology. Processing and use of the products cannot be controlled by us and are therefore exclusively in your field of responsibility.

Our products meet the VDE standards respectively correspond to DIN pages and IEC recommendations.

Attention: Before first design in please contact manufacturer.

The products, described in this catalogue, are designed for connection of bare energy cable conductors (Class 1 & 2) with description of round solid (RE), round stranded (RM), as well as sector solid (SE), sector stranded (SM) and round stranded compacted (RMV) for conductor temperatures up to 90 °C. All conductor filling materials like tapes, yarn, powder or similar need to be completely removed before the installation. A check on basis of the actual existing conductor dimensions by the user is indispensable. This applies also for the application of Class 6 conductors or other special conductor types.

Impact wrenches have to be approved by Nexans! Depending on different conductor material or conductor type, indicated values may differ from test values acc. to IEC 61238-1. The use of fine stranded conductors has to be approved by Nexans Power Accessories Germany GmbH.

Our responsibilities are only those listed in the latest edition of “General terms and conditions for the supply of products and services of the electrical and electronics industry”. We can provide a copy on request.

Our products are mainly delivered in cartons. We only use package materials able to be recycled due to the latest packing system. Collapsible cardboard boxes are not taken back. Please try to order complete standard packages.

Reprinting, even partial, only with special allowance. We reserve the right to alter or modify the characteristics described.
