TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS Transformer Assemblies from 30kVA to 250kVA TRANSFORMERS TRANS Blakley Electrics designs and manufactures transformers in ratings up to 250kVA, with voltages of up FORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORM to 3300V. Transformers can be step-down, step-up or 1:1 ratio; single or three phase; double or auto RS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRA wound. They are typically housed in heavy duty enclosures fabricated from mild steel or stainless steel. Applications include: IT supplies for merchant and military ships; signalling supplies in the rail sector (see NSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFOR data sheet TRDS032 for details of Network Rail approved transformers); LV supplies within National Grid MERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS high voltage HOT sites; isolated supplies for construction sites to ensure separation between temporary and RANSFORMERS TRANSFORMERS TRANSFORMERS TRANSF permanent supplies; step-up and step-down TRANSFORMERS pairs for tunnel and trackside applications; permanent or temporary LV / RLV supplies within large industrial complexes such as dockyards and offshore fabrication ORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORME yards. Transformers are made to order and to quote we need instruction in the following areas. TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANS Ratings FORMERS TRANSFORMERS TRANSFORMERS Transformer cores are manufactured in accordance with relevant TRANSFORMERS sections of BS EN 61558TRANSFORM or BS EN 60076, in virtually any rating from 30kVA to 250kVA, single or three phase. For most applications transformers are TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANS double wound but auto wound transformers can be incorporated when the voltage is being transformed for FORMERS TRANSFORMERS TRANSFORMERS TRANSFORM purely functional purposes. TransformerTRANSFORMERS assemblies are naturally air cooled and continuously rated at an ambient of 25°C (higher ambient temperatures can be TRANSFORMERS catered for if advised at the time of enquiry). For critical RS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRA installations, thermocouples can be embedded into the windings to enable the temperature to be monitored NSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFOR whilst in use. As our equipment is typically used in harsh operating conditions, windings are vacuum varnish impregnated and tropicalised as standard. MERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS Voltages RANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSF Primary and secondary winding voltages need to be specified ORMERS TRANSFORMERS at the time ofTRANSFORMERS enquiry. We are generally able to accommodate TRANSFORMERS TRANSFORME voltages up to 3300V. Tappings can be incorporated if there is TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANS doubt about the exact value of the supply voltage. Tap changing FORMERS TRANSFORMERS TRANSFORMERS is usually a manual operation but tap changing switches can be TRANSFORMERS TRANSFORM incorporated toTRANSFORMERS facilitate easier switchingTRANSFORMERS and access to the tap TRANSFORMERS TRANSFORM FORMERS changing switch is restricted by a padlockable cover. RS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRA Earthing NSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFOR Specifying the secondary earthing arrangement is critical, as is the relationship between the earthing of the primary and MERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS secondary circuits (particularly on 1:1 ratio transformers). RANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSF Inrush Current 100kVA, 1:1 Ratio Transformer for ORMERS TRANSFORME TransformersTRANSFORMERS typically have an inrush TRANSFORMERS current of 10 to 15 times TRANSFORMERS National Grid HOT Site full load. Please advise at time of enquiry if a low inrush current TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANS design is required (and the maximum level of inrush). TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANS Switchgear FORMERS TRANSFORMERS TRANSFORMERS A range of switchgear can be incorporated including isolators TRANSFORMERS TRANSFORM / switch disconnectors, MCBs, MCCBs, Switch Fuses, IMDs and TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANS RCD protection. FORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORM Enclosure FORMERS Enclosures areTRANSFORMERS floor standing and canTRANSFORMERS be vented to IP23 or TRANSFORMERS TRANSFORM non-vented to IP55. Enclosures can be fabricated from mild or RS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRA stainless steel and finished in a range of durable paint finishes NSFORMERS TRANSFORMERS TRANSFORMERS TRANSFOR (stainless enclosures can be unpainted). TRANSFORMERS External chambers can be incorporated to house switchgear or to terminate large MERS TRANSFORMERS TRANSFORMERS TRANSFORMERS TRANSFORMERS or oversized cables.
