The 300/500V Flat Twin & Three Core Cables (Code: FLAT TWIN & THREE CORE CABLES) are specifically engineered to meet the demanding requirements of modern indoor electrical wiring systems. These cables combine durability, space-saving design, and full compliance with international standards to deliver reliable and long-lasting performance.
Manufactured by Jiangsu East Energy Electrical Engineering Co., Ltd. – a trusted and leading provider of electrical system products, cable accessories, and power distribution solutions – these cables strictly adhere to BS6004 standards, ensuring consistent and dependable operation across a wide range of installation environments.
The flat profile of these cables significantly reduces the amount of space required during installation, making them an ideal choice for applications where wiring must be unobtrusive, concealed, or routed through confined areas.
Common installation scenarios include:
Hidden within walls – for clean, aesthetic interior finishes
Embedded in plaster – suitable for new construction and renovation projects
Routed through tight spaces – such as cable trays, conduits, or behind panels
With a strong focus on safety, reliability, and long service life, these cables are built to withstand the rigors of dry and damp indoor conditions. They are suitable for:
Residential buildings – house wiring, lighting circuits, and power outlets
Commercial facilities – office buildings, retail stores, and hotels
Light industrial settings – workshops, control panels, and small machinery
These cables support consistent electrical operation under normal indoor environmental conditions, helping to reduce the risk of wiring failures, electrical fires, and unplanned downtime.

Conductor: Featuring solid copper conductors, the cables offer excellent electrical conductivity, ensuring efficient current transmission with minimal loss. The conductor's solid core enhances stability, reducing the risk of breakage during installation or long-term use.
Insulation: Each conductor is wrapped in PVC insulation, which provides robust protection against electrical leakage and short circuits. The insulation material is resistant to heat and moisture, aligning with the cable’s suitability for damp locations.
Outer Sheath: A durable PVC outer sheath encloses the insulated conductors, offering an additional layer of defense against physical damage, corrosion, and environmental factors. This sheath also contributes to the cable's flat, compact shape, facilitating easy installation in confined spaces.
These 300/500V flat cables are specifically designed for fixed installations in:


Dry indoor areas such as living rooms, offices, and retail spaces.
Damp locations like kitchens, bathrooms, and basements (where moisture levels are controlled).
Installation within walls, under floors, or embedded in plaster, thanks to their flat profile that avoids bulky protrusions.
Their versatility makes them a preferred choice for residential wiring, commercial fit-outs, and light industrial applications where space efficiency and safety are paramount.

The cables operate reliably at a maximum temperature of 70℃, ensuring stability even under prolonged use or moderate heat exposure.
Designed to carry currents ranging from 18A to 54A (depending on core size and installation method), they support a wide range of indoor electrical devices and systems.
The combination of solid copper conductors, PVC insulation, and outer sheath ensures resistance to wear, corrosion, and environmental stress, extending the cable's service life.
