1, to prevent a short circuit fault rats, snakes and other small animals caused by 2, to prevent acid, alkali, salt and other chemicals on the busbar corrosion 3, to prevent maintenance personnel mistakenly charged the gap caused by accidental injury 4, adapt switchgear miniaturization Trend 5, solve the problem of insulation phase busbar groove Dongguan to the crown plastic products: the production of PU tube, PU sling, PVC pipe, PC pipe pc insulating sleeve, silicone tube t8 insulating sleeve, ABS pipe, PP pipe, PE pipe, light pipe, light bars, light guide cable insulation casing, a light guide flat strip, factory direct! Welcome to consult condenser bushing capacitance borders of the bases with adhesive tape manufacture, high mechanical strength, can be mounted at any angle, anti-moisture performance, simple structure and maintenance, no need for casing, the lower borders of the bases can also be turned into a short-tailed formula , reduce its size. The disadvantage is that at high voltage and high-grade materials and process requirements must borders, foursquare is not easy to eliminate the gap, resulting in partial discharge voltage is low. Since the tape condenser bushing and high dielectric loss and low partial discharge voltage, has gradually been replaced by paper Capacity bushing. The use of oil-paper capacitors for the bases, and generally have lower porcelain sets, the lower part of a larger size, more sensitive to moisture, high sealing requirements; the advantages of an insulating material and workmanship easy to solve, dielectric loss pvc insulated casing, good partial discharge performance. Since the 1970s, China has been widely used 110 to 500 kV EHV oilpaper condenser bushing. 1980s, China has developed a plastic impregnated paper sleeve, its capacitance heart sons are vacuum impregnated with synthetic resin, the insulation paper into the bases, and then by heat curing treatment. The performance advantages of both tape and paper Capacity-style casing. Insulating sleeve, insulating sleeve, the cap insulating sleeve provided by the Dongguan City, the crown plastic products Limited. Dongguan City, the crown Plastic Products Co., Ltd. (www.gddgyg.com) strong, credible, in Dongguan, Guangdong wire, pipe, plate manufacturing equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improve the more innovative ideas will lead pipe crown plastic products into the brilliant and you work for a better future!
