Twin and Earth Cable LSZH Flat TPS 2X2.5+E2.5mm² is a flat-type cable designed specifically for indoor electrical wiring, featuring safety, environmental friendliness, and practicality. It is widely used in lighting and power distribution systems of residential buildings, commercial buildings, and public facilities.​ The cable adopts a core structure of "two live wires and one earth wire": 2 phase wires (live wires) of 2.5mm² and 1 earth wire (E wire) of 2.5mm² are arranged in parallel, wrapped in an LSZH (Low Smoke Zero Halogen) insulating sheath, and the whole is flat (TPS design). This structure not only saves installation space, facilitating laying in narrow environments such as wall trunking and floor interlayers, but also reduces the risk of wiring misoperation through clear distinction of core functions (usually phase wires are brown/blue, and earth wire is yellow-green 双色).​ In terms of materials, the conductor is made of high-purity electrolytic copper, which has excellent conductivity, ensuring stable current transmission and reducing line loss; the insulation layer and sheath are made of LSZH materials, which have significant environmental advantages - in high temperature or combustion situations, they will not release toxic halogen gases and a large amount of smoke, which can effectively delay the spread of fire, gain time for personnel evacuation and equipment protection, and are especially suitable for places with strict fire safety requirements, such as hospitals, schools, high-rise buildings, etc. At the same time, LSZH materials have excellent aging resistance and UV resistance, and can adapt to long-term indoor dry or humid environments, with a service life of more than 15 years.​ As a flat TPS cable, its flexibility is better than traditional round cables, with a small bending radius, which can flexibly turn in complex wiring paths, reducing construction difficulty. In addition, the cable has passed strict mechanical performance tests, with strong tensile and wear resistance, and can withstand slight external impact during installation and use.​ In terms of electrical performance, the cable has a rated voltage of 450/750V, meeting the voltage requirements of household and small commercial equipment, with a continuous current-carrying capacity of up to 24A (at an ambient temperature of 30℃), suitable for air conditioners, refrigerators, washing machines and other common household appliances. The setting of the earth wire further strengthens safety protection, which can quickly conduct the leakage current of the equipment into the ground, avoiding electric shock accidents.​ The product is manufactured in strict accordance with international standards such as IEC 60228 and BS 6004, and has passed multiple tests such as insulation resistance, voltage resistance, and combustion performance to ensure the quality consistency of each meter of cable. Whether it is the circuit laying of new buildings or the upgrading of old lines, this cable can provide a reliable wiring solution for indoor electrical systems with its characteristics of safety, environmental protection, convenient installation and stable performance.
