current-limiting fuse tube ,Fusible limitador de tubo，High voltage bushings，Seccionador cut out
filament wound tube, special sleeve for high-voltage arrester, current-limiting fuse bushing is made by impregnating epoxy resin solution with alkali-free fiber yarn and winding it at an angle of 50-60 degrees in the axial direction. This product is widely used for oil immersion. Type transformer, H-class dry type transformer, railway locomotive transformer, main switch with high voltage products such as split switch, reactor, arrester, SF-6 transformer, experimental device, etc., with high withstand voltage, low dielectric loss and low volume , high mechanical strength, no deformation, less water absorption, chemical corrosion resistance and so on. The product can be machined by sawing, cutting, drilling, sleeve drilling, etc. without cracks, delamination, peeling and other defects. Its insulation performance is far superior to traditional ceramic tube products, and it is environmentally friendly and avoids ceramic products. The shortcomings of brittleness during transportation assembly, the explosion-proof strength is much higher than that of ceramic products, and it also avoids the devastating major loss of porcelain tubes once they explode. At present, many well-known manufacturers at home and abroad are upgrading and replacing alternative ceramic products, and the development prospect is very broad. The appearance of the product is generally natural, white, light yellow, medium gray, orange red, light green or light brown. The product has a fiber content (weight ratio) of 70-75%, a density of 2.00 g/cm 3 , a water absorption of 0.02%, a bending strength of not less than 50 MPa, and a vertical layer electrical strength of not less than 8 kV / mm. Provide drawings and require production, or specialize in custom-made products for customers, including: two-step step/grooving/ribbing and punching, etc., into various high-performance insulating structural parts. According to user requirements, the tube can be made into class B, class F. Or grade heat resistant grade products. The products are widely used in oil-immersed transformers, H-class dry-type transformers, on-load tap-changers, reactors, surge arresters, SF6 transformers and other main insulators. Main specifications: Φ8-Φ99, Φ100, Φ110, Φ140, Φ150, Φ160,Φ165,Φ170,Φ175,Φ180,Φ185,Φ190,Φ195,Φ200,Φ205,Φ210,Φ215,Φ220,Φ225,Φ230,Φ235,Φ240,Φ250,Φ260,Φ270,Φ280,Φ300,Φ400,Φ550mm etcs large diameter can be opened Modular customization, telephone consultation, and free printing of pipe logo patterns for customers!
