Oil Immersed Inverted Current Transformers Current Transformer CT

Product Name: Oil Immersed Inverted Current Transformers Current Transformer CT Model NO.: Lvb Series Brand: Ville Shape of Core: Ring Frequency Characteristics: Power Frequency Usage: Single-phase Transformer, Rectifier Transformer, Combined Transformer, Power Transformer, Distribution Transformer Certification: ISO9001-2000, ISO9001 Winding Type: Separated Winding Transformer Cooling Method: Dry-type Transformer Core: Core-type Transformer Phase: Single Application: Power, Instrument Trademark: VILLE Transport Package: Wooden Case Origin: China HS Code: 85 Product Description Introduction to StructureLVB (T) series current transformer has an inverted structure with oil-immersed paper insulation (Please see theleft figure).It is connected in series with electric energy measurement, measuring, relay protection and transient protectionfunctions.Primary coil has a through-type conducting rod structure with good dynamic and thermal stability; its maximumthermalcurrent can be up to 63kA/3s (when primary coil is connected in series).Primary coil passes through the center of secondary coil without flux leakage. Measurement precision can be upto 0.1and0.2S grades.Secondary coil is fixed in an aluminum shielded-case by casting organic materials; secondary measurementandprotection circuits cannot be damaged by insulation breakdown.Optimal capacitor screen bushing is made of a complete piece of imported broadsheet cable paper; it is coiledby anautomatic wrapping machine which is controlled by a computer with high performance. It has atechnological de-centralityand an excellent insulation property. Partial discharge test is carried out under powerfrequency test voltage.Use the automatic vacuum drying treatment system produced by LEYBOLD in Germany, carry out pressure-changingvacuum drying treatment and oiling after a product is assembled completely, and all insulationmaterials are imported fromforeign countries. All these ensure that the dielectric dissipation factor of completeproduct tan is less than 0.3%.External insulation uses a porcelain cover with high strength, optimal surface field intensity together with lowerfieldintensity of internal bushing make the porcelain cover avoid explosion.Secondary outlet box is a complete structure by casting the aluminum alloy; its sealing structure meets therequirement of IP55, which is dust proof, water proof and air permeable; secondary terminal for wiring usesPhoenix special terminal; itis more convenient for operations such as plug-in, pull-out and wiring etc.Connection between components uses argon-arc welding, fill in high pressure nitrogen to detect leakage afterassemblyis complete, so oil penetration and oil leakage caused by oil-immersed products are resolved at root.Use an aluminum alloy cast case, all components including the base, connection box, stainless steel expander,andnameplate etc do not rust forever.It is light and handy with a small volume and light weight.This product is free-maintenance.OUR SALES TEAMOur Services1.Pre sale servicea.make technical solutionb.send quotation, technical data sheet and drawingc.prepare power transmission plan, testing plan and shipment plan2.In sale servicea.supervise the manufacturing schedule totally in accordance with the planb.send photos to customer during every manufacturing process(hold point)c.inform the customer one week before testing.3.After sale servicea.installation and commissioning, training the workersb.quick response within 12 hours any timec.provide 12 months guarantee period normally.FAQ1.
