Why Choose the Cembre H70-H70ST Copper H-Sleeve?
The Cembre H70-H70ST, manufacturer code 2490911, is a professional copper H-sleeve connector designed for creating secure tap and joint connections between copper conductors in electrical installations. Manufactured from high-purity electrolytic copper, it provides a robust and dependable solution for industrial power distribution, panel building and electrical maintenance applications.
Designed for conductors with a cross-section of up to 70 mm² on both the through and branch connection, the H70-H70ST allows conductors to be joined by compression without interrupting the main conductor. Its annealed copper construction supports reliable crimping, while the tin-plated surface helps protect the connector against corrosion and maintain dependable electrical contact.
The H70-H70ST measures approximately 34 × 28 × 17 mm and is designed to operate across a wide temperature range from -50 °C to +150 °C. Its compact H-shaped construction makes it suitable for high-capacity electrical connections where space efficiency, mechanical strength and long-term connection reliability are important.

Reliable Tap and Joint Connections for Copper Conductors
H-sleeve connectors provide an efficient method of creating permanent compression connections between copper conductors. Their H-shaped profile allows a through conductor and branch conductor to be positioned separately within the connector before compression, making them particularly useful when creating taps from an existing electrical conductor.
The Cembre H70-H70ST combines high-purity annealed copper with a protective tin-plated surface to provide a mechanically strong and electrically efficient connection. Its ability to accommodate conductors up to 70 mm² makes it suitable for demanding power distribution and industrial electrical applications where reliable high-current conductor connections are required.
Typical Applications
- Industrial electrical power distribution systems.
- Tap connections from main copper conductors.
- Copper conductor jointing applications.
- Industrial control panels and switchgear.
- Motor and machinery electrical connections.
- Electrical maintenance and repair installations.
