The use of the strap is necessary on all low voltage electrical networks, since it allows the attachment of various equipment and accessories (anchoring and suspension systems, overhead boxes, etc.) to electrical poles.
The different types of straps
The strap can be used to fulfill different functions: fixing of an anchoring system, a box, a case or a sign plate…
Depending on the desired use, the materials that make up the strap as well as the sizes can vary.
To fix equipment on an electric pole, the strap used is made of stainless steel strips combining mechanical resistance and corrosion resistance.
However, there are several steel grades with a slight variation in chemical compounds. These provide a wide range of different steels with different mechanical strengths, elongations and corrosion resistances. These grades are called AISI..
Did you know? The term AISI refers to the :American Iron and Steel Institute.
The strap comes in many different sizes (lengths) and thicknesses. It is the equipment to be fixed on the post that will determine the choice of a strap size: the heavier this accessory will be and will generate mechanical resistance constraints, the thicker and longer the strap must be..
There are generally two standard thicknesses: 0.4mm and 0.7mm.
For the width, the most used dimensions are 10, 13, 16 and 20mm.
