Preformed Line Products' THERMOLIGN® group of products is a specialized line of hardware solutions engineered for high-temperature, low-sag (HTLS) conductors in transmission systems.

While the operating temperatures of conventional conductors are between 90-150°C, HTLS conductors can operate in the 150-250°C range. PLP’s THERMOLIGN® products are designed to withstand continuous operating temperatures up to 250°C, making them ideal for modern power grids that demand higher capacity and efficiency.

Sunray is a direct replacement of PhotoVoltaic (PV) cable, the interconnecting cable used between solar panels in a solar farm. Sunray is the most energy-efficient and cost-efficient photovoltaic (PV) wire on the market. These premium CCA conductors offer 3% greater efficiency than standard cables.

Designed to reduce wildlife and incidental contact, Copperweld® Stingray™ wire is an easy-to-install, covered, CCS high-voltage cable for use between phase conductors and equipment bushings.

ArcAngel is an IEEE-compliant CCS grounding conductor for substation grounding applications where electrical performance is critical, and flexibility is needed while still offering all the benefits of Century products.

Century Grid is Copperweld’s flagship family of grounding conductors and structural cables, installed in the harshest environments for over 100 years. With twice the strength of copper, Century is used in applications where high tensile strength, corrosion resistance, and theft deterrence are required.

ACCC® (Aluminum Conductor Composite Core) cable is an advanced overhead power line conductor that offers enhanced efficiency, capacity, and reliability for electrical transmission. It replaces traditional Aluminum Conductor Steel Reinforced (ACSR) cables and other high-capacity conductor systems.

An ACSR/TW (Aluminum Conductor Steel Reinforced/Trapezoidal Wire) cable is an advanced type of overhead power line conductor specifically designed to carry high-voltage electricity over long distances efficiently and reliably. This cable is a variant of the standard ACSR (Aluminum Conductor Steel Reinforced) cable but features aluminum strands in a trapezoidal shape rather than the typical circular shape.

AACSR (Aluminum Alloy Conductor Steel Reinforced) cable is a type of overhead conductor used primarily in power transmission and distribution lines. It is designed to deliver high tensile strength along with good conductivity, making it suitable for long-distance power transmission under high mechanical stress conditions.

An All Aluminum Conductor (AAC) cable is a type of electrical conductor commonly used in overhead power lines for both primary and secondary distribution. It is made entirely of aluminum, which is known for its high electrical conductivity, light weight, and relatively low cost.

An All Aluminum Alloy Conductor (AAAC) cable is a type of overhead conductor used in power transmission and distribution lines. Similar to the All Aluminum Conductor (AAC), the AAAC uses aluminum in its construction, but with a significant difference: AAAC cables are made from aluminum alloy rather than pure aluminum. This alloy typically includes elements such as magnesium and silicon, which enhance the overall properties of the conductor.

The COYOTE Dome Closure by Preformed Line Products (PLP) is an adaptable and reliable solution for managing fiber optic cables. It is designed to be craft-friendly, offering features that simplify installation and re-entry without requiring special tools. The dome comes in different sizes, including 6.5" x 17", 6.5" x 22", and 9.5" x 28", making it suitable for various applications.
