Core Product Categories
MacLean Power Systems offers a comprehensive range of electrical infrastructure products built to exceed industry standards across four primary categories:
Electrical Clamps for Conductors
The company manufactures an extensive variety of clamps engineered for diverse utility applications. From dead-end clamps to parallel groove clamps, each product is designed to provide reliable conductor retention and mechanical strength. Dead-End Strain Clamps, for instance, are made from high-strength aluminum alloy and boast a mechanical strength of 9,000 lbs. Certain clamps are specifically designed to facilitate tap connections, allowing utilities to connect or divert electrical current from the main line to transformers or other equipment. These clamps are refined through rigorous testing to ensure they can efficiently handle the demanding conditions found in real-world electrical systems.
Advanced Insulator Products and Systems
MPS insulators incorporate cutting-edge technologies like biaxial compression seal, which increases both mechanical strength and environmental sealing. This innovation extends product life and performance even in challenging climates, helping utilities reduce maintenance costs over time.
Modular Fiberglass Bracket Systems
These systems are specifically designed to optimize storage and transportation logistics. By maximizing truck capacity, utility crews can transport more equipment during emergency deployments, significantly reducing response times when communities need power restoration most urgently. MacLean Power Systems also offers innovative modular fiberglass bracket systems that further enhance storage efficiency and speed up storm response efforts.
H-Frame Crossarm Kits with UVMAXX™ Technology
These integrated, all-in-one utility solutions represent MPS’s commitment to simplifying field operations. The proprietary UVMAXX technology enhances UV resistance, extending service life under prolonged sun exposure and reducing the frequency of replacement cycles.
Specialized Clamp Solutions
MacLean Power Systems has developed an impressive array of specialized clamp solutions, each engineered to address specific utility needs and applications:
| Clamp Type | Construction | Application | Key Features |
|---|---|---|---|
| Dead-end Clamps | Malleable iron | No. 6 solid to No. 1/0 stranded copper conductors | Optimal mechanical and electrical performance |
| Duckbill Clamps | Specialized design | Temporary grounding with hot stick operation | Safe application under energized conditions |
| Ground Clamps | Robust construction | Connect steel strand (1/4” – 3/8”) to copper ground wire | Reliable system grounding and fault current discharge |
| SLACAN Guy Clamps | Hot rolled steel bars | Guy wire attachment with parallel grooves | Secure attachment with minimal slip |
| Neutral Conductor Clamps | Ductile iron | #2 ACSR to 336.4 ASC diameter conductors | Durable neutral connections |
Some clamp designs are specifically used for tap connections, allowing electrical current to be diverted from the main line to auxiliary equipment or transformers through secure attachment to insulators. Neutral span clamps, for example, enable the connection of service drops in mid-span, providing a reliable solution for specific utility needs.
Each clamp type addresses specific installation requirements and environmental challenges that utility crews encounter. The use of materials like malleable iron and ductile iron ensures these products can withstand the mechanical stresses and environmental exposure typical in utility applications. Ground clamps, for instance, are used to connect steel strand to copper ground wire sizes ranging from #9 to #4, ensuring secure and efficient grounding in various scenarios.
Surge Arresters and Protection
Surge arresters are a vital part of any electrical infrastructure, designed to protect both people and equipment from unexpected voltage surges. Built to withstand the harshest electrical events, these devices efficiently discharge excess energy to ground, preventing damage to sensitive systems and ensuring continuous operation. Whether the surge is caused by lightning, switching operations, or temporary overvoltages, MacLean Power Systems’ surge arresters are engineered to handle a variety of tasks with reliability and precision. These arresters are installed on circuit breakers inside residential homes, inside pad-mounted transformers, on pole-mounted transformers, on pole-mounted riser poles, and in substations, ensuring comprehensive protection across the grid.
Each surge arrester is carefully designed and built to meet the rigorous demands of modern electrical networks. By integrating these protection solutions, businesses can refine their electrical systems, striving to minimize downtime and avoid costly equipment damage.
