BASOLIT® Insulator Cement is used world wide in all climes.
There are different Insulator Cement types:
AV 40 (Q8)
The materials differ in composition with different results in viscosity, mechanical strength or semi conduction.
Assembly of fittings with ceramic insulators
Insulators for transmission lines
BASOLIT® is supplied ready for use in plates 400 x 400 x 70 mm and a weight of about 18 kg.
BASOLIT® should be stored in a dry and clean storage. There is no limit in durability.
BASOLIT® has to be melted for use with a temperature between 135 and 145 degree centigrade.
Impact of heat should be smooth from bottom and sides. Continuous stirring should be done, to avoid sedimentation.
Overheating for example from the bottom, leads to a change of viscosity – BASOLIT® becomes glutinous, the colour becomes red-brown.
Pouring should be done in two steps shortly after each other. It is necessary to observe, that the temperature is between 135 and 145 degree centigrade, that the BASOLIT® is well stirred and that insulator and fitting are free of pollution and humidity. Poor stirring leads to smaller mechanical strength.
After casting the surface can made smooth by a short re melting with a hand held air heater.
Tests, especially mechanical test should be done min. after 24 hours.
Specific electrical resistance: electrical non conductor
Linear expansion: 0,024 %
Casting temperature: 135 – 145 degree C
Setting time: hardens after casting
Working temperature range: -40 to +90 degree C
Storage: no restrictions
Flash point: 240 (VDE 0165) degree C
Resistant to all acids, alkalis, caustic solutions and any kind of water. Not hygroscopic. Oil and grease can dissolve minimal amounts of the sulphur surface. Sulphur is not considered toxic. Sulphur dioxide which is produced at combustion causes severe irritation of eyes and respiratory ducts. Protective measure during at combustion: eye and lung protection. Extinguishing agents: Water vapour, carbon dioxide, foam.
The material is supplied ready mixed and ready for use (in plate form 400 x 400 x 70 mm, weight ca. 18 kg). It is essential to observe that the material is well stirred before pouring. Poor stirring leads to sedimentation which alters the properties of the material.
