Latest company news about Oil-filled large-logarithmic telephone lines have the following significant advantages in communication engineering

Excellent waterproof and moisture-proof performance.
The oil-filled design (HYAT model) and polyethylene jacket effectively block moisture penetration, making it suitable for direct burial, pipeline installation, or installation in humid environments, keeping the cable interior dry for extended periods.

Anti-interference and signal stability.
The oil-filled structure reduces crosstalk between pairs. Combined with the copper conductor (0.4-0.7mm diameter) and insulation material, it ensures stable audio and digital signal transmission, supporting digital signal transmission up to 2048kbit/s.

Strong mechanical protection.
Heavy armored models (such as the HYAT22 and HYAT53) feature steel or aluminum tape layers for enhanced tensile and compressive strength, making them suitable for outdoor applications in complex terrain or where mechanical protection is required.

Wide environmental adaptability. Operating temperature range covers -30°C to 60°C. Select models (such as the ZRC-HYAT) are flame-retardant certified, meeting the needs of various climates.
