The advantages of 100-pair armored telephone cables (such as the HYA100×2×0.5 model) are primarily reflected in the following aspects:
Mechanical Protection and Durability
The armor layer, made of steel tape or steel wire, can withstand external impact, compression, and stretching, effectively protecting the conductor structure from physical damage.
Anti-Interference Capability
The metal armor layer reduces external electromagnetic interference and ensures stable signal transmission, making it particularly suitable for use in complex electromagnetic environments.
Environmental Resistance
It is moisture-resistant and corrosion-resistant, suitable for harsh environments such as underground, underwater, and chemical sites, extending its service life (up to 30-50 years).
Safety
The armor layer protects against rodent damage and accidental cutting, reducing the risk of leakage and short circuits.
Applicable Scenarios
It is suitable for urban telephone trunk lines (with metropolitan area network coverage exceeding 70%), programmable switch wiring, and low-speed monitoring signal transmission. It can be installed overhead, in ducts, or directly buried (armored models required).
