GENERAL Tension clamps are used to tension conductors and earthwires and musttherefore satisfy the most stringent requirements.There are two basic systems of tension clamps, viz:1. Detachable clamps, such as wede-type tension clamps, thimbles, bolted type tension clamps, which allow for subsequent adjustment, and2. Non-detachable clamps, such as compression dead-end clampswhich require absolute matching to the conductor length.

Obviously our design therefore fulfills the following:

Holding forces • The clamps must take up the maximum conductor strain, i.e. they must take up the holding forces stipulated in the regulations, which as a rule lie between 85% and 95% of the ultimate conductor strength.These requirements do not apply to clamps which are used in switchingsubstrations.The components which transmit the compressive force must be designedso that no unacceptable squeezing of the conductor may take place.

Vibrations • Vibrations of the conductors are dangerous, especially at the conduc-tor entrances of the clamps. Safety requirements can be met by a light-weight construction of the clamp and a trumpet shape of the terminati-ons, resp. a gradual increase of conductor compression.

Corona • Good corona and radio interference voltage (RIV) behaviour due to rounded shapes.

Short circuit capability • The short circuit capability is excellent due to a narrow ranged groovewhich leads to a big contact area.The connecting parts of the clamps are adjusted to the requirements.

Corrosion resistance • Maximum corrosion resistance is achieved by using a clamp materi-al that matches with that of the conductor, for example a corrosion-resi-stant AlMgSi alloy for conductors made of aluminium, aldrey, etc.

Electrical losses • Electrical power losses (eddy current losses) are kept to a minimumby an adequate design.

Standards The connecting bolts acc. DIN 48073/5.6 or 8.8.Split pins are made of stainless steel or tinned copper.Clevis eye connections acc. DIN 48074 resp. IEC 471.

Hot dip galvanising Steel hardware is hot dip galvanised in Mosdorfer’s own plant.Galvanising can be done in accordance to national and international stan-dards.

Wedge type tension clamps trunnion type,for aluminium-, al-alloy-, ACSR-, AACSR- and alumoweld conductors

Wedge type tension clamps have a universal usage in all areas of overhead line construction. They are also used in substations.For conductors with a diameter greater than 15,9 mm clamps with jumperattachments can be provided.The two halves of the body are kept together because of the shape of the wed-ges.

Marking of compression dead endclamps and joints

Compression dead end clampsCompression dead end clamps are used in all areas of overhead line construction,that is both for substations and for transmission lines.The greatest possible strength is achieved with compression dead end clamps; forexample: with ACSR conductors the load-bearing steel cable is held separately, sothat even conductors having an extremely high steel proportion can be clampedfor high-tensile stresses.There are different compression systems in use: circumferential compression andindentation for hexagonal compression, the latter being the most popular.Compression can be achieved with a variety of tooling systems provided the com-pressive force of the press is sufficient and the characteristics of the inserts andclamps match.Compression dead end clamps are tapered at the conductor inlets to allow gra-dual force transmission.Normally the jumper terminal is bolted to the clamp flag; for smaller types, designscomprising a welded jumper can be supplied.Compression fittings are available for every conductor type and size.To achieve the best results the clamps are individually adapted for each conductorand therefore we need the following information, preferably on a data sheet, forthe conductor:– code name or identification of the conductor– material and cross sections– number and diameter of wires– ultimate breaking load

Compression fittings are filled with compound and sealed. For larger types thecompound is delivered in separate tubes.

Compressing systems:There are basically 2 compression systems which use hexagonal compression, asdetailed below:

system 1 system 2

compression: offset (continuous) continuous

taper: internal taper external taper

We are able to supply clamps according to both of the above systems, but haveshown in detail in this catalogue only those clamps belonging to system 1, i.e. having internal taper.Clamps according to system 2 are available on request.

Bolted type tension clamps for aluminium-, al-alloy-, ACSR-, AACSR-conductors

Bolted type tension clamps are used in substations and distribution lines.Consequently it is always necessary to give the exact data concerning con-ductor and stresses.With this clamp type the conductor can be passed onwards uncut.Fitting is extremely simple by tightening the clamp bolts to the prescribed tigh-tening torque.
