Abstract:

Water soluble polymers are classified according to highly varied families of products of natural or synthetic origin and have several uses. Among these families, synthetic polymers are mainly used for bonding of boards and paper laminates which is used as an insulation for high voltage power transformers. The three main characteristics of water soluble polymers used in laminates are the molecular weight, concentration and internal structure. In general, the efficiency of the polymer will be greater if it posses longer molecular chain which inturn depend on their molecular weight. In addition t

Abstract:

The tropical climate of Indonesia, which has moderately high rainfall, has an impact on the output of outdoor insulators. The presence of chemical particles, pollen, and salt in the air will bind to the insulating material's outer surface and settle, resulting in crystallization that allows the insulating material's surface roughness to increase. One of the insulators that are being produced is an insulator made of epoxy resin. The injection of fillers is used to further improve the durability of the outdoor epoxy resin insulators installed in tropical climatic conditions. Epoxy resin from bis

After a century of practice, cellulose insulating polymer (insulating paper/pressboard) has been shown to be one of the best and most widely used insulating materials in power transformers.

Considering the complex environment of the transformer, it is not enough to improve the single performance of the insulating polymer.

The paper investigates the theory of electrical breakdown channel formation in polymeric dielectrics. The process of operating electrical networks is quite complex, since dielectric materials lose their insulating properties under the influence of electric field intensity, which causes the destruction of molecular bonds. This phenomenon is called dielectric breakdown, or a violation of its electrical strength and loss of dielectric properties, followed by the formation of a breakdown channel with high electrical conductivity. Additional factors, such as insulation cooling conditions, external

Introduction: Thermal insulating coatings are increasingly being introduced into construction practice for internal and external finishing enclosing structures and pipelines. Thermal insulation coatings are usually made based on polymer binder and mineral fillers. The durability and stability of the properties of heat-insulating materials depend on the type of binder. As a rule, polymers are used as a binder: epoxy resin; silicone rubber; urea-formaldehyde resins; aqueous dispersed polymers - styrene-butadiene, polyvinyl acetate, and acrylate (acrylic and styrene-acrylic).

Moisture is one of the important reasons for the deterioration of cellulose polymer insulation, which seriously threatens the safe and stable operation of bushing. It is significant to study the polarization and depolarization behavior of oil-immersed cellulose polymer insulation with different moisture condition under higher voltage. Based on polarization/depolarization current method and charge difference method, the polarization/depolarization current, interfacial polarization current and electrical conductivity o

Abstract:

The study presents the results of the composition development for producing heat-insulating fire-resistant coating for concrete and metal surfaces of various construction facilities. The composition includes binder - siloxane rubber, filler - hollow carbon microspheres, and flame retardant additive – electroplating sludge. Siloxane rubber improves heat-insulating properties of the obtained coating. Hollow carbon microspheres used as fillers in the amount of 20-50 wt.p. decrease heat insulation of the coating. Flame retardant additive in the amount of 10-15 wt.p. provides self-extinction effect

Abstract:

Abstract Electrical cable fires are significant hazards, prompting recent efforts to reduce cable flammability by blending halogen-free flame-retardant materials with the base polymer; however, combining flame-retardant sheaths with non-flame-retardant insulations is a common practice in the cable industry. Sheath breakage, and in turn, exposure of the non-flame-retardant insulation to the external heat source is a severe fire risk that can be observed both in vertical flame spread standard tests, like EN 60332 and UL 1581, and laboratory scale measurements, such as cone calorimetry measuremen

Abstract:

The use of polymer insulation to mitigate galvanic corrosion was examined for bolted joints of AZ31B Mg alloy and carbon fiber-reinforced composite. To assess the corrosion behaviors of bolted joints with and without polymer insulation, solution immersion and salt spray exposure (ASTM B117) tests were conducted, and the corrosion depths and volumes were determined for the joint specimens after the tests. The polymer-insulated bolted joints exhibited much lower corrosion depths and volumes, highlighting the effective mitigation of galvanic corrosion. The reductions of joint strength in the post

A brand new phenomenon, namely, electrical conduction via soliton-like ultra fast space charge pulses, recently identified in unfilled cross-linked polyethylene, is shown for the first time to occur in insulating polymer nanocomposites and its characteristics correlated with the electromechanical properties of nanostructured materials. These charge pulses are observed to cross the insulation under low electrical field in epoxy-based nanocomposites containing nanosilica particles with relative weights of 1%, 5%, 10%, and 20% at speeds orders of magnitude higher than those expected for carriers

Ensuring high power, efficiency and reliability of induction motor operation while providing small weight– size parameters represents an up-to-date problem. One of the factors limiting the reduction of weight–size parameters when increasing capacities of induction motors is the failure of the insulation system. Therefore, there is a strong need for studying the issues of slot fill when designing an induction motor, taking into account an increase in the heat resistance class of electrical insulation systems.
