Austin Insulators, Inc. and Longview
Inspection have entered into a strategic alliance joining the most
innovating manufacturer of insulators and transformers used in MF
and VLF antennae systems with the largest full service field nondestructive
testing (NDT) organization in the Americas. The combined team offers
resources to meet both your nondestructive testing and maintenance
needs. Both companies bring their unique technology and depth of
experience to the alliance and can now offer even more value to

constant loads. These components are exposed to the elements, sometimes,
hostile. Prudent and frequent examination, maintenance and repairs
are a must in order to protect your investment and to prevent costly
downtime and accidents.
is used during the guy wire inspections. This instrumentation measures
the loss of metallic area and localized faults during the test.
The loss of metallic area, or LMA can be caused by internal or external
corrosion, wear, damage, etc. Local faults, or LF can be due to
internal or external faults such as broken wires, pockets of corrosion,
etc. Test results are stored in a computer. Strip charts of data
are then generated and interpreted by the inspector. Any defects
or loss of metallic area is noted. A field test report, explaining
the general condition of each guy rope is left with the client prior
to the inspection crew leaving the job site. Formal computerized
reports will be sent to the client in approximately two weeks after
the inspection is complete.
EXAMINATION METHODS such as ultrasonic, magnetic particle,
liquid Penetrant and
radiography can also be utilized to detect defects in fittings, clamps,
attachments, foundations and ground anchor structures to name a few.
will help to extend the life of the guy wire and its components.
The internal portion of a guy is subject to corrosion and a the
application of a good penetrating lubricant will protect the inside
and outside of the strand especially in the areas under fittings
and, at the same time, allow the rope to "breathe" so
that water, in the form of condensation can easily find its way
out of the structure.
of guy wires is necessary in order to insure adequate support of
the antenna structure. Longview uses hydraulic equipment to check
the tension of the ropes. When tensioning the guy wire, the current
condition and strength is taken into consideration and the proper
adjustments are made.
SYSTEMS wear out eventually, gradually losing work
capability throughout their useful lives making periodic inspections
and maintenance necessary. Defects detected during an inspection
can help pinpoint the factors leading to and eventual guy wire and/or
component failure. Many system components have to be replaced due
to damage caused by other, outside sources. These inspections can
help the client to diagnose and correct these damaging conditions
before an unfortunate incident occurs. The life of your investment
can be extended once these outside sources are identified and corrected.
