BUSHINGS
-
Piedmont porcelain dry-type bushings: Available in ratings from 15 through 38kV, with BIL ranging from 110 through 200 and up to 3000 amperes. Suitable for both outdoor and indoor applications.
Capacitance-Graded Oil Free Bushings: Equipped with silicone sheds, rated from 15kV through 69kV, with BIL ranging from 110 through 350 and up to 4000 amperes. Ideal for vacuum circuit breakers, switchgear, and Current Transformers.
-
PBI Capacitance-Graded Bushings: Designed for Transformer and Oil Circuit breaker applications, featuring a proven design based on a series capacitor core using aluminum foils and high dielectric paper impregnated with epoxy resin. These bushings meet all ANSI/IEEE standards for outdoor apparatus bushings and offer superior thermal performance.
PBI CRC Bushings: Engineered to meet end user needs, providing lighter weight than traditional porcelain and non-breakable sheds for added safety and ease of installation.
-
PBI Disconnect Bushings: Crafted from Capacitively graded cores and Cycloaliphatic Epoxy for enhanced performance compared to porcelain. Our bushings ensure minimal discharge (<2pC) at 200% rated voltage.
-
Our repair and maintenance services include complete refurbishment of old-style magna blast breaker bushings, as well as those from brands like Westinghouse, ABB, ITE HK breakers and switchgear, Federal Pacific, Allis Chalmers, and many others.

Pole Line Hardware
-
Polykeram Insulators offer a host of advantages, making them an increasingly popular choice:
Economy: Produced in low-cost rubber molds and curing quickly at room temperature, Polykeram Insulators eliminate the need for lengthy drying and firing cycles. This energy-efficient process reduces inventory and storage needs while offering quick turnaround times for new parts.
Electrical Performance: With externally attached caps eliminated, Polykeram Insulators boast increased strike distance.
Strength: Innovative designs with threaded inserts allow for special high-strength versions of standard insulators. Their high impact strength reduces breakage during transport and at job sites, making them ideal for earthquake-prone areas.
Design Flexibility: When molded products are your preferred insulation solution, Polykeram by Piedmont Bushings & Insulators provides unparalleled flexibility.
INSTRUMENT / CURRENT TRANSFORMERS
Step into the realm of innovation with Piedmont Bushings & Insulators, LLC, your one-stop shop for toroidal wound current transformers and sensors. With over 40 years of experience under our belt, we fuse electrical insulation design prowess with unparalleled expertise, ensuring our transformers are as sturdy as they are sophisticated.
Forget the woes of insulation failures – with our transformers, they're a thing of the past. Choose from our extensive range of standard current transformers, or let us whip up a custom design using our in-house computer wizardry. We don't just stop at standard – we redefine it.
Crafted from top-notch silicone steels, we handcraft and anneal our cores, wrapping them with precision winding. Whether it's taping, molding, or encasing in our signature epoxy or urethane resins, each transformer undergoes rigorous testing to meet ANSI or IEC standards. And rest assured, we keep a permanent record of every serial number and performance, supplying certified test reports upon request.
So, if you're in the market for a BHK, BG MC, MCS, or any other CT or sensor, dial us up at 864-476-6360. Let Piedmont Bushings & Insulators take your CT requirements to the next level – because with us, transformers aren't just tools, they're works of art
Line Sensors
At Piedmont Bushings & Insulators, LLC, we're all about bringing the spark to Power-Line Sensing. Our line sensors come in three voltage classes, offering you an electrifying experience without the hassle of line cutting.
Line Post Sensors: Unleash the Power!
Designed with linemen in mind, our line sensors feature a lay-in primary conductor groove and swing link primary clamp, making installation a breeze—no line cutting or primary taps needed! And don't worry about interruptions—we've got your customer service covered.
Our shielded, non-inductive resistive divider ensures a smooth ride with linear output voltages that stay proportional to primary voltage, rain or shine. Low voltage AC outputs? No problem! They can be open-circuited or shorted without a zap, thanks to our cutting-edge design.
And here's the shocker: Every sensor undergoes rigorous testing, including a thrilling partial discharge test up to 125% of max voltage. With our insulation system exceeding >2 picocoulombs of discharge at 125% of max voltage, you can trust in our quality.
