Howard Industries Excels at Delivering

Exactly What Our Customers Want.

Life-Cycle Cost

Reduction

Howard IndustriesCustomer Assistance Teamexcels at helpingcustomers find ways toreduce cost. Using activity-

based cost analysis

techniques, ourcommercial and technicalexperts help customersanalyze costs throughoutthe transformer supplychain, identifying andeliminating activitieswhich add cost but havelittle or no value.

Quality and Reliability

Built into Every

Transformer

Higher quality meanslower failure rates andthat translates into loweroperating and mainte-nance costs. Higher qualityalso means customers canreduce cost by reducing oreliminating incomingreceipt inspection andtesting.

At Howard Industries ourQuality AssuranceProgram is designed toachieve the high level ofquality required by ourmost demandingcustomers. Abandoningthe traditional manufac-

turing-only focus, we havecreated a quality systemthat links all aspects of thecompanys operationsincluding Marketing,Engineering, ManagementInformation Systems,Manufacturing, Shippingand Accounting to makesure that not only ourproducts, but everythingwe do for our customers isof the highest quality.

Howard Industries qualitymanagement system hasearned ISO-9001 certifica-tion. ISO-9001, the mostcomprehensive standard inthe internationallyrecognized ISO-9000 series,covers design, manufac-

turing and servicingsystems. This achievementdemonstrates HowardIndustries commitment tocontinuous qualityimprovement.

Designs Optimized for

Superior Performance

and Economy

Our design philosophy isto provide our customersexactly what they want.That means transformersthat are individuallydesigned in preciseaccordance with eachcustomers specifications.Each transformer design is

optimized to satisfy thecustomers needs at thelowest possible cost.

Howards ProductAutomated Design System(PADS) is driven directly

by each customersspecifications to insure thatall the necessary

requirements are satisfied.PADS synthesizes eachtransformer design andproduces all criticalmanufacturing documents.PADS then links with asophisticated computer-integrated-manufacturing

(CIM) system to automati-cally carry-out fabricationon the factory floor. ThePADS and CIM systemseliminate manualprocesses and theirinherent inefficiency anderror, and make it possibleto quickly modify andcustomize transformerdesigns.

Advanced

Manufacturing

Howard transformers aremanufactured in thelargest, most advancedfacility of its kind. The 1.6million square foot Laurelplant is the result of a

recent three-year, $50million expansion project,which saw the introduc-tion of the latest and mostsophisticated robotics andautomated processequipment available.

Three-Phase Pad-Mounted Transformer Features

Howard Industries liquid-filled three-phase pad-mounted transformers are anexcellent choice for any commercial or industrial underground distribution system.Typical applications include manufacturing facilities, refineries, office buildings,schools, hospitals, restaurants, warehouses, and retail stores. All Howard Industries

transformers are designed, built, and tested in an ISO-9001 certified facility inaccordance with applicable industry standards.

Howard three-phase pad-mounted transformers are available in capacities from30 to 10000 kVA, with high-voltage ratings from 2400 through 34500, and low-voltageratings from 208Y/120 through 8600. All designs feature fully enclosed tamperresistant terminal compartments and can be supplied with dead-front or live-frontconstruction (Space-Saver 3TM style available with dead-front construction only), forradial or loop feed applications.

A wide range of features and accessories is available to satisfy almost any specialrequirement, including fuses, surge arresters, gauges, controls, cooling fans, pressurerelief devices, load-break switches, and high-voltage tap switches. In addition to thestandard mineral oil, alternate insulation fluids such as R-Temp, silicone, and seed-

based vegetable oil are available for special applications.
