WebAbstract. To clarify the effects of drying temperature on the hygroscopicity and mechanical performance of MUF resin-impregnated wood, we investigated the water vapor adsorption capability, modulus of rupture (MOR), modulus of elasticity (MOE), and surface hardness of MUF resin-impregnated wood treated at 60, 80, 100, 120, 140 °C. WebRIP transformer bushings are oil-free transformer bushings with a solid active part made of resin-impregnated paper and a condenser control. The air side housing is available in a porcelain version or as a silicone composite material. This bushing with dry filling is designed for rated voltages of up to 1200 kV and rated currents up to 6000 A. WebPitchwood is the resinous wood which decays last from dead conifers. It can be found on the ground where conifer tree trunks have fallen and decayed. The parts of the deadwood that would form the knots in lumber, i.e. the places where branches entered the trunk, are impregnated with resin which has the combustibility of wood soaked in lighter ... new world catering tauranga
