Connector, connectors and again connectors
Cable Protection Conduits.
Metallic flexible tube increases temperature and fire resistance, mechanical, tensile strength, abrasion and impact resistance.
Connectors and boxes can be supplied with cable protection coverage made of steel.
It can be a conduit or an external braid of galvanized steel (stainless steel upon request).
Conduits of polyamide (nylon) are available as well; their dimensions are bigger than conduits of steel, but they have a very good chemical resistance and sometimes they are cheaper.
Halogen free polyester braided sleevings can instead offer flexibility and high temperature resistance, 150°C working temperature, 200°C melting point.
Steel braid. In the case of metal braid, a further option is to put a second external sheath in order to protect the metal for outdoor applications, facilitating cable cleaning and preventing corrosion, but the diameter becomes bigger.
Steel flexible tube, compared to armoured (armored) cable, offers a better protection against crushing and could be even used just for a partial length; on the other hand its external diameter is bigger.
Applications with welding machines, construction equipment, agricultural machinery, food industry machinery, earth moving machines, lifting or air platforms, warehouse and moving goods plants.
Another interesting application is to prevent rodent (rats, mice) and termite attacks. In many areas steel armouring (armoring) is the best way to stop or reduce serious damage.
