TBE / TBE/D / MAL / RJA aluminium cable lugs and sleeves, 16–500 mm²
Country: Spain · Model: TBE / TBE/D / MAL / RJA
The aluminium lugs TBE and TBE/D and the sleeves MAL and RJA terminate and join aluminium conductors of power cables by crimping, for cross-sections of 16–500 mm². They are made of aluminium with a purity of at least 99.5 %, and the tube cavity is factory-filled with neutral grease. They are used in 0.4 kV networks and in transformer substations.

Description
TBE is a tinned lug made from tube per DIN 46329 for cross-sections from 16 to 300 mm². TBE/D is machined from bar and its whole surface is electrolytically tin-plated; it also complies with DIN 46329, is rated for 25–500 mm² and is intended primarily for underground cables. The MAL sleeve with a central stop dividing it into two equal parts complies with DIN 46267 and is rated for 25–300 mm². The RJA sleeves, including reducing ones for different cross-sections, are made of aluminium alloy with a purity of at least 99.5 % with a central partition that centers the conductor, and they comply with UNE and carry the AENOR mark. The reducing RJA joins Al–Al and Al–Cu; the aluminium conductor enters the larger part and the copper one the smaller part, and after installation the ends are sealed against moisture. The grease in the tube prevents oxidation and keeps the contact resistance low. They are crimped with manual, hydraulic or battery-powered tools with hexagonal dies; for T, TL and TBE there are manual pliers SF-P70 and SF-P150.
How to choose
The choice is set by the cable cross-section and the type of connection. Up to 300 mm², TBE is suitable; for cross-sections up to 500 mm² and underground lines, TBE/D is taken. Two aluminium ends are joined by MAL or RJA, and for Al–Cu the reducing RJA. If an aluminium cable is connected to a copper busbar, look at the bimetallic TBF and the tinned TDC with cross-sections up to 400 mm².

FAQ
What aluminium conductor cross-sections are TBE and TBE/D designed for?
TBE is rated for 16–300 mm², TBE/D for 25–500 mm². Both comply with DIN 46329.
Why is there grease inside the aluminium tube?
The neutral grease prevents oxidation of the aluminium and keeps the contact resistance low in service.
Can aluminium be joined to copper with an RJA sleeve?
The reducing RJA allows Al–Al and Al–Cu connections. The aluminium conductor is inserted into the larger part of the sleeve and the copper one into the smaller part.
What is used to crimp TBE lugs?
Manual, hydraulic or battery-powered tools with hexagonal dies, for example SF-P70 and SF-P150 pliers.
Which standard describes the MAL sleeve?
The dimensions comply with DIN 46267, cross-sections from 25 to 300 mm².
