Cembre 2507440 (2A37-2M14) heavy duty two-hole electrolytic copper compression cable lug with electro-tinned finish, suitable for 185 mm² copper conductors and dual M14 stud connections.
£27.10
The Cembre 2507440 is a premium heavy duty two-hole copper tube compression lug (type 2A37-2M14) engineered to provide secure, low-resistance electrical terminations for demanding industrial, utility and medium-voltage applications. Manufactured from high-purity annealed electrolytic copper with a durable electro-tinned finish, it delivers outstanding electrical conductivity, corrosion resistance and long-term mechanical reliability. Designed for 185 mm² copper conductors with dual M14 fixing holes, it provides maximum mechanical stability in high-current installations.
Part of the renowned Cembre 2A-2M Heavy Duty range, this compression cable lug features a double-length barrel without an inspection hole, helping prevent moisture ingress while providing superior crimp performance. The extended two-hole palm delivers increased resistance to vibration and electrodynamic forces, making it ideal for substations, switchgear and critical power infrastructure.
Designed for substations, switchgear, renewable energy installations, industrial machinery and electrical infrastructure, the Cembre 2507440 provides dependable cable terminations for indoor and outdoor installations, including medium-voltage systems up to 35 kV.
Heavy duty two-hole compression lugs are designed to create secure electrical connections capable of withstanding vibration, mechanical stress and high fault currents. The extended two-hole palm provides greater stability than conventional single-hole terminals while maintaining low electrical resistance.
The Cembre 2507440 combines annealed electrolytic copper, electro-tinned corrosion protection and a moisture-resistant double-length barrel to deliver dependable long-term performance in substations, switchgear, renewable energy installations and industrial power distribution systems.
