Introducing the New Millennium Line— Transformer Pads for the 21ST Century

Highline Products is proud to introduce a new line of 15”, 24” and 32” transformer pads. Our innovative, patented, design results in a product that is extremely strong and durable, yet lightweight. These products are manufactured at our ISO9000 certified plant using compression molding tools and a specially formulated SMC (sheet molding compound). This process assures consistent product quality as well as other benefits such as:

  • UV protection throughout the entire product, versus surface only protection
  • of a spray up fiberglass box
  • Superior side wall strength which helps reduce sidewall deflection
  • Up to a 40% weight reduction from traditional box pads
  • Easy installation
  • Fire retardant
  • Rapid production — which yields shorter lead-times

Through our innovative manufacturing technique, Highline Products can now offer its compression molded product line with an expanded number of top openings including openings customized to your needs. Thus, Highline compression molded products are now available to meet a wider range of customer needs.

Durability Over the Long Haul

Northeast Underground Guidelines (NEUG) call for box pads with a minimum safety factor of 2x for the normal life span of a transformer—30 years. Recent testing of 30-year old Highline box pads, returned from the field, revealed they still carried loads up to 7,000 pounds while complying with deflection criteria of NEUG. The New Millennium Line is an extension of this history of quality, while pricing is in line with the current needs of our customers.

Install your box pads with confidence knowing that you are using the best in the industry!

COMPRESSION MOLDED PRODUCTS

HIGHLINE SPRAY-UP PRODUCT SERIES

Compression Molding of SMC (sheet molding compound)

This molding technique involves compressing material containing a temperature-activated catalyst in a heated match metal die using a vertical press. The matched metal dies define the outer surface of the part being made.

The molding process begins with the delivery of high viscosity uncured composite material to the mold. Mold temperatures typically are in the range of 275- 350 Deg F. As the mold closes, composite viscosity is reduced under the heat and pressure approximating 1000 psi. The resin and the isotropically distributed reinforcements flow to fill the mold cavity.

While the mold remains closed, the thermoset material undergoes a chemical change (cure) that permanently hardens it into the shape of the mold cavity. Mold closure times vary from 30 seconds up to several minutes depending on part design and material formulation. When the mold is closed the pressure exerted by the press tonnage forces the resin, gel coat and UV inhibitor throughout the reinforcement. The resulting part is extremely strong, durable and consistent.

Advantages

  • Compression-molded box pads are twice as stiff as spray-up boxes. They are also superior in every area of strength, offering 50-60% greater flexural strength, 20-30% greater tensile strength and 30-70% greater impact strength than spray-up products.
  • Consistency-- wall thickness is consistent throughout the molded part, whereas sprayup construction is difficult to control and is dependent on the operator.
  • UV Protection- Compression-molded box pads have integral molded U.V. protection throughout the entire product; not just on the gel coat surface, which is the case with spray-up.
  • Speed of Production.
  • Class A Surface- Both inside and outside surfaces are smooth.

Disadvantages

  • High initial capital investment- match metal molds are very expensive thereby limiting compression molding to only high-volume parts.

Spray-Up

Spray lay-up is an open mold process that uses mechanical spraying and chopping equipment for depositing the resin and glass reinforcement. Chopping equipment consists of a spray gun attachment, which chops glass fiber into predetermined lengths and projects it to merge with the resin mix stream. This causes the resin and chopped glass to be deposited simultaneously to the desired layer thickness on the mold surface (or on the gel coat that was applied to the mold.

The mold (female mold) is first coated with a wax to ensure removal after curing. A layer of gel coat is then sprayed on to the mold to form the outermost surface of the products. The polyester resin is applied with a spray gun that has a glass chopper attachment.

Layers are built up and rolled out on the mold as necessary to form the part. The spray gun has separate resin and catalyst streams that mix as they exit the gun.

Advantages

  • Low start up cost-- molds and equipment are relatively inexpensive.
  • Variable sizes-possible to modify mold sizes, thus enabling a wide range of available sizes.

Disadvantages

  • Only one side of the product is smooth.
  • UV protection and gel coat is only on the top surface.
  • Inconsistent product thickness--the product is only as good as the operator.
  • After manufacturing, part must be trimmed which leaves raw edges that are susceptible to environmental ingress.

Conclusion

Each manufacturing technique has unique capabilities and limitations. Overall a compression-molded part is the most desirable because you are guaranteed a consistently strong and durable product each and every time. Unfortunately, for low-volume production, compression molding is not effective. Currently the spray-up process is the best alternative for low-volume parts.

Highline Products is proud to introduce a new line of 15”, 24” and 32” transformer pads. Our innovative, patented, design results in a product that is extremely strong and durable, yet lightweight. These products are manufactured at our ISO 9000 certified plant using compression molding tools and a specially formulated sheet molding compound

October 26, 2004—WALTHAM, MA—Highline Products announced the completion of its development of the New Millennium single-phase box pad line. The development of an improved version of the company's compression molded products commenced three years ago. The goal was a significant reduction in the weight of the products, while still offering customers products that were 100% compliant with industry guidelines for strength, integrity and deflection over an extended life time. The result of this work is a patented design for box pads of 15", 24" and 32" heights that are 40% lighter than most products on the market. The new product line was developed in conjunction with Metis Design; a Cambridge, MA based consulting firm specializing in composite structures and our manufacturing partner, Molded Fiberglass Company.

Paul Tannenbaum, President of Highline Products, views the New Millennium product line as an extension of the high-quality products that Highline has provided to its utility customers since 1971. He said, "The box pads will be manufactured using a new family of match metal tools at Molded Fiberglass's, ISO 9000 certified plant in Ashtabula, OH. The nature of the New Millennium design allows Highline to offer an expanded number of top openings on the box pads. Thus, almost every utility will now have the opportunity to purchase compression molded parts with their consistent quality in strength, laminate structure, and external appearance at competitive prices."

In other developments, Highline completed the construction of a full family of molds for the production FRP/polymer splice boxes in sizes up 30" x 48" as well as a family of all polymer flat pads. Mr. Tannenbaum stated, "This development is consistent with Highline's overall strategy of product line expansion in order to more fully satisfy customers' needs."

 

Pull boxes can be used next to the Control Buildings.
for extra cable training room. Pull Boxes can stand alone and be used by themselves with conduit for pulling cables.These are just a few examples of Pull Boxes with different cut outs, hole sizes, and configurations.
Highline can manufacture custom Pull Box layouts with customers request. Are used in the underground distribution of power and signals. They provide access to the buried lines and allow an area for splicing and pulling of cable or housing of in-line equipment.
