Pillar 5: Medium & High-Voltage Power Systems
Power-side components for utility-scale solar and energy projects — medium and high-voltage cable terminations, collector system hardware, substation components, and transmission line materials.
Power-side components for utility-scale solar and energy projects — medium and high-voltage cable terminations, collector system hardware, substation components, and transmission line materials. We specialize in sourcing critical, application- specific parts that are rarely stocked by traditional distributors, helping EPCs and contractors keep projects on schedule when it matters most.
What We Supply
Three product families that cover the medium and high-voltage side of utility-scale energy projects — from collector system terminations and substation hardware to transmission line components and the specialized parts that keep complex power systems running.

FAMILY 01
Collector System Components
Collector system components are the critical connection points between the solar array and the utility interconnect — and where sourcing delays hit project timelines hardest. This family covers T-bodies, splices, termination kits, junctions, and the accessory parts that complete a collector system. We stock cold-shrink and heat-shrink termination kits for shielded cable rated 5kV through 35kV in indoor and outdoor configurations, sized to match the conductor and insulation system on your project. PCWC is actively building inventory depth in this category — these are specialized products rarely stocked by traditional distributors, and we treat them as a core part of our supply strategy.

FAMILY 02
Substation Components
Substations are among the most complex and component-intensive parts of any utility-scale project — and the parts list runs deep. This family covers main power transformer parts (including bushings), HV/MV breakers and disconnect switches, HV/MV surge arresters, capacitor and reactor bank parts, instrument transformers (CTs, VTs, CCVTs, CITs), S&C fuses and disconnects, grounding transformers, HV/MV fuses, MV/HV cable, and the metering and protection equipment found in the substation control building —including SEL items and related hardware. Whether you're sourcing for a new-build substation or tracking down replacement parts for an existing facility, PCWC has the manufacturer relationships and the willingness to dig for what you need.

FAMILY 03
Transmission Line Components
Transmission line work involves a wide range of parts and components — from insulators, cross arms, and cable to connectors and OPGW (Optical Ground Wire) hardware. PCWC has built supplier relationships across this category and can help you source the materials your project requires. OPGW in particular sits at the intersection of our power and fiber expertise — combining ground wire function with fiber optic communications in a single conductor, it's a product that calls for a supplier who understands both sides. Whether you're building a new transmission line or maintaining an existing one, bring us the spec and we'll find what you need.

BUILT FOR THE "OH SNAP!" MOMENTS
Hard to source is what we do
Collector system parts, substation components, and transmission line hardware are the items that quietly stall projects when they're back-ordered everywhere else. Whether you need a termination kit, an instrument transformer, or OPGW hardware that no one else stocks, our team will source, quote, and ship from Minden. Bring us the spec — we'll find what you need.
