Product Introduction
Engineering Grade Cable is the core component of construction and industrial power distribution. This YTTW Construction Grade Power Cable, as a professional Engineering Grade Cable, adopts a double-layer insulation structure of mineral insulation + XLPE cross-linked polyethylene, with a Class A fire resistance rating (950~1000℃) and a continuous working temperature of up to 250℃, specially designed for low-voltage power distribution scenarios in construction projects and industrial plants. As a typical Industrial Fireproof Cable, it is covered with a corrosion-resistant copper sheath, featuring excellent anti-aging and anti-wear performance, and can maintain stable power supply for more than 90 minutes in fire, meeting GB 50217 Code for Design of Electric Power Engineering Cables and IEC 60332 flame retardant requirements. Meanwhile, this cable is a Multi Core Structure Cable, supporting flexible selection of 1-5 cores (single core cross-section 2.5-400mm²). The multi-core stranded design reduces eddy current loss, adapting to complex laying environments such as building high-voltage wells and industrial production lines, without the need for additional pipe protection, greatly reducing construction costs. This Cable is halogen-free and heavy metal-free, releasing no toxic gases when burned, with a service life of more than 50 years under normal working conditions. It is the first choice of Engineering Grade Cable for commercial complexes, data centers, chemical plants and other scenarios, and the flexibility of this Cable makes it more suitable for low-voltage power distribution needs of different powers.

Core Product Advantages
High-Demand Scenarios:
It passes strict voltage withstand, fire resistance and aging tests, and can be directly used in key circuits such as building main power distribution and emergency lighting, with long-term operation stability reaching the international leading level.
Industrial Fireproof Cable Safety Protection:
Featuring an exclusive double-layer insulation + copper sheath structure, it does not burn or short-circuit at a high temperature of 950℃ and releases no toxic smoke, meeting the fire safety requirements of high-risk scenarios such as industrial plants and chemical zones.
Multi Core Structure Cable Flexible Adaptation:
This cable supports 1-5 cores on demand. The multi-core integrated design reduces the number of cable layings, adapting to scenarios with limited space such as building high-voltage wells and industrial equipment distribution boxes, improving the neatness of the power distribution system.
Weather & Corrosion Resistant, Maintenance-Free:
The copper sheath has excellent acid, alkali and salt corrosion resistance, and can be directly buried underground or laid in humid environments without additional protection. No replacement is needed for 50 years under normal use, reducing later maintenance costs.
Low Loss & High-Efficiency Transmission:
High-purity oxygen-free copper conductors have high conductivity, XLPE insulation layers have low dielectric loss, and the multi-core stranded structure reduces electromagnetic interference, with power transmission efficiency 8%-10% higher than ordinary cables.
Easy Installation, Time-Saving:
The flexible structure design has a small bending radius, adapting to the laying needs of building corners and narrow equipment spaces. It can be cut without professional tools, greatly shortening the construction period.
