Unsheathed insulated cable

Unsheathed insulated cables use an insulation layer that directly covers the conductor, with no separate outer sheath on the outside. They are mainly used for internal connections, power distribution, and control circuits of electrical equipment at AC 450/750V and below. Compared with sheathed cables, their structure is simpler, making them suitable for wiring occasions with requirements on installation space and bending radius. The products cover two types of applications: flame-retardant and fire-resistant. The flame-retardant type is used to reduce the risk of flame spreading along the cable, while the fire-resistant type can maintain power supply for a certain period under fire conditions, so it is often used in power stations, high-rise buildings, subways, tunnels, smart buildings, critical factories, complex buildings, and railways. We support customization of conductor material, cross-sectional area, insulation material, color, length, printing, packaging, and product identification. Before purchasing, you can contact us to confirm the specific model and configuration.

FAQ

What is the difference between unjacketed insulated cable and jacketed cable?

Unjacketed insulated cable has only an insulation layer covering the conductor, with no separate outer jacket; jacketed cable has an additional jacket outside the insulation layer. The unjacketed structure is simpler and is suitable for scenarios such as internal equipment connections, power distribution, and control. The specific selection depends on the installation environment and usage requirements.

What is the rated voltage of this cable?

The rated voltage is AC 450/750V and below, suitable for electrical equipment connection and building wiring. If the project voltage level is different, please contact us to confirm available models.

How to choose between flame-retardant type and fire-resistant type?

The flame-retardant type is mainly used to reduce the risk of flame spreading along the cable; the fire-resistant type can maintain power supply for a certain period of time in the event of a fire, suitable for important facilities with special fire protection requirements, such as power stations, high-rise buildings, subways, and tunnels, etc. For the specific choice, you can contact us to confirm based on the project's fire protection requirements.

Can conductor material, cross-sectional area, and length be customized?

Yes. We support customization of conductor material, cross-sectional area, insulation material, color, length, printing, packaging, and product identification. Please provide the specific dimensions and quantity, and we will assist in confirming the configuration.

How to confirm price, MOQ, delivery time, and certification information?
