Electrical Containment Trunking Installation

When running a business or managing commercial premises, the safety and organisation of your electrical infrastructure often sits in the background - until something goes wrong. Cable containment systems such as trunking, conduit, and cable trays are essential in around 90% of commercial and industrial electrical installations, ensuring safety, organisation, and compliance with regulations.

At HV Electrical Services, we provide professional electrical containment installation services across all types of commercial and industrial premises. Our fully trained engineers understand that proper cable containment is about far more than just tidying cables away. It protects your electrical infrastructure, ensures compliance with safety standards, and makes future maintenance significantly easier.

Cable containment refers to the systems used to house, protect and organise cables within a building. Rather than having insulated cables running loosely or clipped directly to walls and ceilings, cable containment systems provide secure pathways that keep everything neat, accessible, and safe.

These systems come in various forms - from rigid metal conduit for industrial environments to plastic trunking for offices, and ladder-style cable trays for larger installations. Poorly managed or exposed cabling is one of the leading causes of electrical hazards in buildings, making cable containment a critical safety feature.

The right cable containment solutions depend on your specific needs, the environment, and the type of cables being carried. We assess each project individually to recommend the most appropriate systems for your premises.

Different environments and applications require different approaches to cable management. Understanding the main types helps you make informed decisions about your installation.

Trunking

Trunking consists of rectangular channels, typically made from PVC or metal, that house multiple cables in neat runs along walls or ceilings. Modern trunking systems are designed to handle today's high-capacity data and power requirements, reducing the risk of overheating and cable damage.

The main advantage of trunking is how it provides easy maintenance access. When you need to add new cables or inspect existing ones, simply removing the cover gives you immediate access to everything inside. A well-designed cable management system can reduce cable installation time by up to 40%, as trunking allows multiple runs to be managed neatly in one pathway.

Mini trunking works particularly well for smaller cable runs or data cabling in office environments. Floor trunking offers another option where cables need to cross open spaces without creating trip hazards. These cable containment solutions ensure both safety and a professional appearance.

Conduit

Conduit systems use rigid or flexible tubes to protect cables, with each length of conduit connected using appropriate fittings and brackets. Metal conduit provides excellent mechanical protection and is widely used in industrial settings due to its durability and fire-resistant properties, offering extra protection for high-demand environments.

Rigid conduit delivers the highest standard of protection for cables in harsh conditions or where mechanical damage poses a significant risk. Flexible conduit allows for easier routing around obstacles and connects equipment that moves or vibrates during operation. Both forms of cable containment help protect cables from environmental damage.

Cable Trays and Ladder Systems

For installations requiring substantial cable capacity, cable trays and ladder systems provide open pathways that support large numbers of cables. These cable management systems allow cables to be laid in organised layers with proper separation, which helps maintain the integrity of both power and data cabling.

The open design ensures excellent ventilation, preventing heat buildup that could damage cables or create safety risks. Installation of these cable containment systems requires careful planning to ensure adequate support at the correct intervals and appropriate cross sectional area for the cable load.

Installing cable containment not only improves safety but also makes future upgrades and maintenance far quicker and more cost-efficient. The benefits extend across safety, compliance, and operational efficiency.

Safety and Protection

Cable containment systems protect cables from physical damage, moisture, and environmental factors that could compromise electrical safety. They prevent accidental contact with live cables and reduce the risk of fire by keeping insulated cables organised and properly ventilated.

When cables run through containment rather than being exposed, the risk of damage from everyday activities drops significantly. This protection is carried through every part of the installation, from the main distribution board to the final connection points. Proper cable management helps protect cables throughout their entire route.

Compliance with Regulations

Cable containment systems are often a legal requirement in commercial premises to ensure compliance with building regulations and health and safety standards. We install all containment in accordance with current wiring regulations and British Standards.

Meeting safety standards is not optional in commercial and industrial environments. Our team ensures every installation is carried out to the highest standard, with proper documentation to demonstrate compliance. As a SafeContractor approved company, we maintain robust health and safety procedures across all our electrical work.

Easy Maintenance Access

Trunking sections can be opened quickly when you need to add new cables or trace existing circuits. This easy maintenance access saves time and reduces disruption during maintenance or upgrades. Businesses often save money in the long run with proper cable containment, as they reduce cable wear, minimise the chance of faults, and extend the life of electrical infrastructure.

Without cable management systems, adding new services often means disrupting finished surfaces or running cables on show. Proper containment designed with future needs in mind means minimal disruption when your electrical requirements change.

Professional Appearance

Trunking provides a clean, professional finish, which is particularly important in offices, retail units, and customer-facing environments where exposed cables can harm appearance and safety. The neat, organised look of properly installed cable containment reflects well on your business and creates a safer environment for staff and visitors.

We approach every cable containment installation project with careful planning and attention to detail. Our process ensures the finished installation meets your specific needs while maintaining the highest standard of workmanship.

Initial Assessment

We start by understanding your requirements, examining the space, and identifying the best routes for cable containment. This includes considering current needs and potential future expansion. Our fully trained engineers assess factors like the location of power sources, the path cables need to take, and any environmental considerations that might affect the choice of materials.

Design and Planning

Based on the assessment, we design cable containment solutions that provide secure cable routes with adequate capacity. We select appropriate materials for the environment - PVC trunking for standard areas, metal systems where additional protection is needed.

Planning also considers the support structures required. Brackets must be positioned at the correct intervals to maintain support along the entire cable run, and we ensure proper capacity in terms of the cross sectional area available for cables. Effective cable management starts with thorough planning.

Professional Installation

Our fully trained engineers install containment systems to deliver both functionality and a professional appearance. We use the right tools and techniques to ensure secure fixing, proper alignment, and neat jointing at corners and junctions.

Cable pulling through containment requires care to avoid damage. We maintain proper separation between power and data cabling where required, and ensure all cables are secured appropriately within the containment. Our installation methods protect cables at every stage, with minimal disruption to your ongoing operations.

Testing and Handover

Once installation is complete, we verify that everything meets safety standards and functions as intended. We provide you with documentation of the installation and guidance on maintenance access points should you need them in the future.

Selecting suitable cable containment systems depends on several factors. The environment plays a key role - industrial settings often require more robust protection than office spaces. The range of cable types being carried affects the choice too, as data cabling may need separation from power cables.

We help you navigate these decisions based on our expertise in different types of installations. Whether you need simple wall trunking for a small office upgrade or a comprehensive cable tray system for a new warehouse, we recommend cable management solutions that deliver value without unnecessary complexity.

We bring extensive experience to every cable containment installation. Our engineers understand the technical requirements and the practical considerations that make installations work well long-term.
