Connector for bare Al/Al lines 25-150 / 25-150 mm SL30.1

Bare Line Clamp – a reliable connection for installers and users

The SL30.1 clamp is a component designed for safe and effective branching of power lines and connecting transformers under voltage. Made of durable aluminum, it provides a durable and reliable connection of aluminum conductors with a cross-section of 25 to 150 mm². It is a key element in the construction and maintenance of medium-voltage networks, and its use allows for minimizing interruptions in energy supply.

Design and application in practice

The SL30.1 clamp is characterized by a through clamping channel for both the main and branched conductor, which facilitates assembly and ensures secure clamping of the conductors. The design allows operation under voltage, which is particularly important when servicing existing lines without the need to disconnect them. This makes it possible to quickly restore power after work is completed. The clamp is compatible with aluminum conductors, making it an ideal solution for most electrical installations in Poland.

• Line branching: Enables the creation of safe and durable branches of overhead lines.
• Transformer connection: Used to connect transformers under voltage, minimizing downtime in energy supply.
• Live work: Provides the ability to perform service work without disconnecting the power supply.
• Material compatibility: Designed for connecting aluminum conductors (Al/Al).
• Conductor cross-section: Supports a wide range of conductor cross-sections – from 25 mm² to 150 mm² for both the main and branched conductor.
• Compliance with standards: Meets the requirements of IEC 61284 standard, guaranteeing safety and reliability.

Additionally, if it is necessary to connect a copper (Cu) conductor with an aluminum one, the PSS830 sleeve can be used, ensuring optimal conductivity and minimizing the risk of electrochemical corrosion. This clamp is widely used both in new installations and during the modernization of existing power networks.
