At Nitronics Ltd, we manufacture large format wiring looms for some of the UK’s most demanding applications, supplying cable harnesses used in emergency and specialist vehicle conversions where reliability is critical.

With almost 40 years of experience in electronic manufacturing and wiring harness assembly, our team produces high-quality looms for vehicles that protect communities and keep essential services operating every day.

Whether the application is a police vehicle, ambulance, fire appliance, highways maintenance vehicle or another specialist conversion, every loom is manufactured to the highest standards and fully inspected before leaving our facility.

Wiring Looms Built for Mission-Critical Vehicles

Emergency service vehicles rely on complex electrical systems to power equipment that can save lives.

Our experienced production team manufactures wiring looms capable of supporting:

• Police vehicle conversions
• Ambulance electrical systems
• Fire and rescue vehicle wiring
• National Highways maintenance vehicles
• Utility and service vehicles
• Mobile command units
• Specialist commercial vehicle conversions
• Custom fleet vehicles

Each loom is manufactured to customer drawings and specifications, ensuring complete compatibility with the finished vehicle.

Designed for Reliability

Large vehicle wiring looms often contain hundreds of individual connections across multiple circuits.

Nitronics manufactures assemblies incorporating:

• Multi-core cable assemblies
• Power distribution wiring
• Signal wiring
• CAN Bus wiring
• Connector assemblies
• Fuse and relay wiring
• Custom breakout looms
• Protective sleeving and conduit
• Heat shrink identification
• Full cable identification and labelling

Every assembly is built using quality components sourced from trusted manufacturers to ensure long-term reliability in demanding operating environments.

Manufactured to the Highest Standards

Quality is built into every stage of production.

Our manufacturing process includes:

• Detailed build documentation
• Controlled manufacturing procedures
• Crimp inspection
• Cable identification
• Continuity testing
• Visual inspection
• Quality assurance checks
• Customer-specific documentation where required

Where customer projects require additional functional testing, Nitronics can also design and manufacture bespoke test equipment to validate finished assemblies.

Supporting Emergency Vehicle Manufacturers

We understand the challenges faced by specialist vehicle manufacturers:

• Tight production schedules
• Complex engineering changes
• Low-to-medium production volumes
• Prototype builds
• Repeat production
• High reliability requirements

Our flexible manufacturing capability allows us to support projects from initial prototype through to full production.

Complete Electro-Mechanical Manufacturing

Nitronics offers far more than wiring loom manufacture.

Alongside large format cable assemblies, we also provide:

• PCB Assembly (PCBA)
• Box Build Assembly
• Mechanical Assembly
• Industrial Control Panel Building
• Electronic Component Kitting
• Product Programming
• Functional Testing
• Custom Test Rig Design
• Supply Chain Management

This allows customers to reduce their supplier base while simplifying project management.

Manufactured in the UK

All production is carried out at our UK manufacturing facility by an experienced team committed to delivering quality, consistency and on-time delivery.

From a single prototype loom to ongoing production contracts, Nitronics works closely with customers to ensure every assembly meets specification and performs reliably in service.

When lives depend on vehicle reliability, every connection matters.
