AEI Cables is highlighting the need for the supply chain to be aware of the various pieces of legislation and guidance in the selection of cables to help make Britain’s buildings safer.

The systems powered by these cables – including smoke and heat extraction systems – assist fire services in firefighting and a safe evacuation in the case of life safety.

The company has been communicating the importance of following the technical guidance for the selection and installation of cables for Category 3 Control fire performance cables under the revised British Standard BS8519: 2020. These cables reduce harmful smoke, toxic gases and flame spread in the event of a real fire.

At the same time, AEI Cables has been raising awareness of the Building Safety Act 2022 which makes new demands on the supply chain in the interests of safety and governance.

Stuart Dover, general manager of AEI Cables, said: “These are important pieces of guidance and legislation which have been introduced for the right reasons to add further levels of safety to the supply chain. “We can’t emphasise enough how important it is to get the selection of cables right for these applications. If these systems fail because the cable is not able to function properly then the consequences are apparent. Lives and property are at stake here.”

Spelsberg’s Lifeline range of enclosures help ensure safety for up to 90 minutes in the event of a fire by enabling critical systems to continue operation.

Protecting cable junctions, connection boxes, and distribution boards, the Lifeline enclosures allow alarms, lighting, and fire suppression system to operate even under flame and extreme heat.

The lightweight, highly durable polycarbonate enclosures enable flexible wall-mount installation and retrofit in buildings and tunnels.

In the event of fire in a building or tunnel, the function of alarms, smoke detectors, and fire suppressant devices is vital. It’s also crucial for some safety systems to continue operation long after a fire has commenced. This includes water booster systems to supply extinguishers, as well as smoke and heat extraction systems, through to evacuation-able fire brigade elevator systems.

To protect the electrical supply to these systems, the enclosures that secure cable junctions, connections, and distribution boards, must provide a barrier to extremes of heat and flame for up to an hour or more. Concrete has traditionally been used as a barrier to encase electrical wiring, but the drawback is a lack of flexibility in installation, and subsequent retrofit.

Alternatively, Spelsberg’s Lifeline system provides up to 90 minutes fire protection in a flexible and highly durable enclosure that can be externally mounted on building or tunnel walls. This enables fast and straightforward installation and retrofit of fire-protected devices and cabling whenever required.

Spelsberg’s fire protection enclosures use heat and fire-resistant materials to achieve electrical functional integrity. Certified between E30, E60, and E90, this guarantees functional integrity of the enclosures for at least 30, 60, or 90 minutes, assisting continued electrical supply to connected devices and are tested in accordance with DIN 4102-12, the European Standard for fire resistance of electric cable systems required to maintain circuit integrity.
