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

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.

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

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.
Drawing
1 - Spray Lay-up
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

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.
