ABB Switzerland Ltd, Micafil offers a wide range of rotor slot insulation for different shapes and material combinations.
Resolam02® or Resolam03®
Made of one or several layers of polyamide (Nomex) laminated at high pressure and temperature to provide high mechanical flexibility and toughness as well as very good thermal material properties. A Vetresit strip may be laminated for mechanical enforcement. Due to precise moulding slot insulation made of highly flexible Resolam can be easily fitted in position.
Vetresit consists of several layers of heat - resistant epoxy resin reinforced with glass fabric laminated at high temperature and pressure. High mechanical strength, good resistance to heat and moisture, low dielectric losses and high electric strength are major features of Vetresit.
Vetresit is used to produce rigid slot liners.
Vetrelam is a laminate consisting of epoxy resin reinforced with glass fabric and aromatic polyamide fibre paper (PA), optionally with trackresistant top layers. Vetrelam is also available with interleaved polyimide film for superior electrical performance and reliability. Fibre glass reinforced outer layers are responsible for the mechanical strength of the material. Layers of tough PA substantially reduces the compressive and shear stresses caused by deformation. Vetrelam is a practically deformation - free insulating material, with superior electrical, dielectrical, tracking - resistant, and thermal properties. It is odourless and extensively resistant to solvents.
