Four lifting Bolted-on terminal compartment (18" or 24" deepdepending on KVA) with removable front sill. 3. Hinged, lift-off cabinet penta-head bolt/padlock handle operates acam assembly which is part of the 3-point door latchingmechanism. (A hex-head bolt is available.)5. For live front construction, externally clamped highvoltage porcelain bushings with a single eyebolt,clamp-type connector (accommodates #6 AWG solidto 250 MCM stranded conductors).6. For dead front construction, externally clamped highvoltage bushing wells for loadbreak or Lightning arrester mounting pads (live front only).8. Tank ground pads (1 in HV, 1 in LV).

Steel high/low voltage compartment One 1/2" penta-head bolt must be removed from theflange formed on the steel high/low barrier beforethe HV door can be opened (1/2" hex-head boltavailable as an option).11. Externally clamped low voltage bushings withthreaded copper stud for full load current below2100 amps. Externally clamped integral low voltagebushings for current above 2100 amps. NEMA spadesprovided per ANSI hole Fill plug and self-actuating pressure relief Drain neutral ground Five-legged core/coil cover bolted onto tank top (protected by weathercover).18. Panel-type NEMA safety paint finish process applies a durable, corrosionresistant finish to the product. The multi-step processincludes an epoxy primer uniformly applied bycationic electrodeposition and a urethane top Features:Primary Termination Externally-clamped bushing wells with loadbreak ornon-loadbreak inserts.

It is designed to improve operation and tobetter withstand its outdoor environment. New manufac-turing equipment has allowed ABB to fabricate a flip-top cabinet design to better serve the needs of ourcustomers. Material choices consist of both carbon steeland stainless improvementfeatures of the new cabinet designinclude: One piece sloped cabinet weather cabinet weathercover has a fourdegree sloped surfaceto shed all moisture tothe rear of the trans-former. Both the handholeweather cover and thefull tank weather coverhave a four degreesloped surface to shed water. The fulltank weather coveroption extends beyondthe rear of the transformer to insure all moisture isdirected away from the top of the tank.

9 The cabinet weather cover support arm is free floating and locks into place automatically. This allowsthe linemen to use both hands when raising the reaching into the compartment is necessary tosecure the cover in place. The cabinet weather cover can be rotated beyond centeror easily removed for better access into the the cabinetcompartment. The capability of pulling cables fromabove was a feature requested by utilities. The interface between the sidewalls and the cabinetweather cover has been redesigned to better receivethe weather cover when closed. This new interfaceminimizes surface contact to prevent the rubbing of paint. This cabinet design hassuccessfully passed allindustry tamper resis-tance Guidelines forTesting EnclosureIntegrity, the designpassed pry tests, pulltests, wire probe tests,deflection tests, and theoperation test.

The design is easier tohandle, install and maintain. The discreet profile of theMTP is ideal for commercial applications such as banks,stores and MTP features a hood and removable sill instead ofdoors. The design allows easy access for installation andmaintenance of the ABB MTP meets the following industry standards:IEEE TR-1 IEEE , Rev.
