What Is UL10269 High Voltage Hookup Wire?
UL10269 high voltage hookup wire is a single-conductor appliance wiring material (AWM) built with a tinned stranded copper conductor and PVC insulation. It is rated 1000 V and 105 °C, references UL 758-2021, and is supplied in sizes from 26 AWG to 4/0 AWG. The wire is designed for equipment internal wiring where a 600 V hookup wire does not provide enough voltage margin, including control cabinet power connections, charging equipment, high-temperature appliances and PV inverter internal wiring.
This is not an outdoor photovoltaic cable and not a power transmission cable. It is an internal AWM lead for panel wiring, equipment harnesses and control lines. The construction, current reference values and voltage rating are intended to help OEM engineers, control cabinet builders and maintenance teams confirm whether the wire can be used inside a specific enclosure.
Construction and Materials
The conductor is tinned stranded copper. Tinning helps the copper resist oxidation, while the multi-strand construction keeps the wire flexible enough for routing through crowded enclosures and harness paths. The conductor and insulation are stated as compliant with RoHS 2.0 and REACH.
The insulation is a PVC environmental insulation material described as UL 105 °C PVC. It is produced with low eccentricity and uniform wall thickness, which helps prevent current breakdown through the insulation wall. The wire carries VW-1 / FT1 flame rating. Surface printing is clear and includes meter marking as supplied.
Colours are made to order. Available colours include red, black, white, blue, yellow, green, brown, grey, orange, purple, pink and yellow/green. The reference standard for the product is UL 758-2021.

Storage temperature is −10 to 40 °C. Operating ambient temperature is −15 to 105 °C. These two values describe different conditions and should both be checked against the equipment environment.
Where UL10269 Wire Is Used
This wire is used for industrial equipment internal wiring, control cabinets and power connections. In control cabinets, it can connect relays, terminals and power supplies where the design requires a 1000 V rated internal lead. In charging equipment, it is used for internal connections where higher voltage margin and flame-rated PVC insulation are needed inside the enclosure.
Other applications include high-temperature appliance internal connections, signal lines, equipment internal wiring and electrical equipment control wiring. In new energy applications, it is used for PV inverter internal wiring, new energy vehicle harnesses and related equipment internal connections. The wire is not intended as an outdoor PV cable; it is an AWM hookup wire for use inside equipment enclosures.
Selection and Installation Notes
Select the AWG or nominal cross-section by the equipment voltage rating, the current at the actual ambient temperature, and the installation conditions. The tables give reference current at 30 °C. Actual current capacity depends on bundling, ambient temperature, ventilation and the temperature rating of nearby components.
For installation, strip the PVC insulation without nicking the conductor, and use terminals or splices rated for the selected conductor size. Support the wire so that terminations are not under strain. The supplied data does not list a minimum bending radius, so confirm the routing path and bend requirements against the actual enclosure layout before installation.
Custom configurations are available on request. Colours are made to order and include red, black, white, blue, yellow, green, brown, grey, orange, purple, pink and yellow/green. Packaging is available in 100 m, 305 m and 610 m coils depending on size; larger cross-sections are supplied on 50 m or 100 m coils.
Certification, Standards and Available Configurations
The supplied documentation references UL 758-2021. The conductor and insulation are stated as compliant with RoHS 2.0 and REACH. The flame rating is VW-1 / FT1. The withstand test value is 3000 V AC per minute, and insulation resistance is 10 MΩ/km at 20 °C.
Available configurations include sizes from 26 AWG to 4/0 AWG, made-to-order colours, and the packaging options listed above. Customization is available on request. For engineers replacing an existing internal lead, confirm the AWG or mm², voltage rating, temperature rating, colour and coil length before ordering.
Why This 1000 V Hookup Wire Fits Your Equipment
If the design calls for a 1000 V rated internal lead rather than a 600 V hookup wire, this UL10269 wire provides the higher voltage rating in a single-conductor PVC-insulated AWM construction. The 105 °C rating, VW-1 / FT1 flame rating and 3000 V AC per minute withstand test are relevant for control cabinet power connections, charging equipment and PV inverter internal wiring.
For harness shops and OEM production, the stranded tinned copper conductor supports routing inside crowded enclosures, and the size range from 26 AWG to 4/0 AWG covers small signal and control leads through larger power connections. To confirm whether this UL10269 high voltage hookup wire fits your equipment, send the required AWG or mm², colour, coil length and operating conditions through the quote form.
