High Voltage Systems Design. Safe, Engineered Solutions for Demanding Power Applications

D&K Wiring offers specialised expertise in the design and manufacture of high voltage (HV) systems, delivering safe, reliable, and high-performance solutions for demanding electrical applications. With over 25 years of experience in wiring and power system design, we support industries where voltage, current handling, and insulation integrity are critical.

Our team works closely with clients to design HV assemblies and wiring solutions tailored to specific operational environments and safety standards. Whether for transport, energy, industrial, or specialised machinery applications, we engineer systems that meet both functional and regulatory requirements — without compromise.

​

We have deep experience with HV cable routing, insulation, terminations, shielding, and connector selection, ensuring performance even under high load, thermal, or environmental stress. Our HV solutions are designed to handle voltages typically ranging from 1kV to 35kV, depending on the application.

​

All systems are designed and built in our UK facility, ensuring tight control over quality, safety compliance, and testing. We offer end-to-end support, from initial concept and specification development through to prototyping, manufacturing, and validation testing. We also integrate client-specific test procedures where required, providing full traceability and peace of mind.

​

Our collaborative approach means we work as part of your engineering team, offering practical insight to improve system efficiency, reduce installation time, and enhance maintainability — all while meeting the highest standards for insulation, clearances, and fault protection.
