Tip: Master Unimax Al
Standard: DIN 48 072-1,
EN 61238-1; EN 61238-3
MAREL Master Unimax Al is used to connect bare LV or MV conductors of the same or different cross-sections. The conductors can be made of aluminum (AAC), aluminum alloy (AAAC) or aluminum conductors steel reinforced (ACSR). MAREL Master Unimax Al is made of extrusion profiles and the inside grooves are serrated, which improves mechanical pull-out strength and provides high-quality electrical contact (the grooves are made in such a way that aluminum oxide from the conductor surface is decomposed, which reduces transiant resistance between the clamp and the conductor). The body of the clamp is made of aluminum alloy of high tensile strength and resistance to corrosion. The clamp is equipped with one or two shear head nuts. Its design enables fast, easy and reliable installation and there are no parts that can fall off when working at height.
NOTE: At Customer request the clamps can be delivered with hot-dip galvanized or stainless steel bolts.
