1 Tap Changer Type MHM Specification, Assembly and Materials Descriptions General Specifications Remarks available in one, two or three phase application multi layer types upon request shaft length is fixed as sizes 91 and 11 mm driving mechanism can be either on the edge or in the middle of the phases connection diagrams (on Page ) can be applied in any variation to all types are bolted together with supports under transformer cover and allow strong construction Steel Parts Polyamide Parts Steel Parts Aluminium Parts Materials available in stainless or mild steel galvanizing upon request mild steel parts are cadmium or zinc plated Materials Nylon / superior mechanical properties against all acting forces / strong against UV lights available in stainless or mild steel galvanizing upon mild steel parts GAISi12(Cu) are cadmium or zinc lated request Polyamide Brass Parts NYLON / superior CuZn0Pb2 mechanical (CW1N) propeties / F DIN against 1 all acting forces Aluminium Copper Parts Parts GAISi12Cu / anodic E-Cu F2 oxication DIN 000 upon request Insulator Parts Brass Parts Paper phenol - plastic resin based laminates / HP 201. class of DIN Cu ZN0Pb2 MS 0 F DIN 1 / available in tin, silver or cadmium plated Transformer Cover Thickness 10 mm - mm ( spacer rings with each 1 mm) Copper Parts E - Cu F2 DIN 0 00 / available in tin, silver or cadmium plated Current 0 A / A / 120 A Insulator Parts Paper phenol - plastic resin based laminates, HP 201. class of DIN aluminum parts can be protected by anodic oxidation Upon Request mild steel parts supplied in stainless steel brass and copper parts are either tin- or silver-plated Operating Instructions For each operation, the handle must first be pulled axially in the direction of the user in order to be subsequently rotated to the desired position. After being turned, the handle drops into the intended position by means of a high tension spring. Each position is precisely marked by a notch. This process is clearly marked on control knob as; LIFT - TURN - SWITCH ON (can be engraved in any language) Current Contact inner dia.

3 Handle Directions and Numbering Combinations Handle direction A1 Clockwise direction Handle direction B1 Counterclockwise direction Numbering Combinations all MHM tap changers can be paired by superimposing several tap changers whose purpose built steel brackets are assembled by nuts and bolts depending on the diagram adopted, the user can: either operate the tap changers with one shaft or operate part of the tap changers with one shaft, and the other part with another shaft the position of the coupling taps shaft and the position of the setting taps shaft has to be specified Note: It is essential, when ordering, to quote dimension W the minimum of which to be set in each case depends on the insulation conditions and on the position of the different tap changers Doc-Nr.: DATA tap changer type MHM_ENG Created: Revised: Language: ENG / 1
