DYJY 5KV D refers to the buried cable used for the runway assist lamp circuit
Other than that, it's a 6kV cross-linked polyethylene insulated and polyethylene sheathed dripless cable, just like conventional cables.
Aid Lighting Cable for Airport Runways Detailed Description
Airport Guidance Lighting Cable - Airport Guidance Lighting Cable: DJ-JJKR-0.6/1KV
Introduction to lighting cables for airport guidance lighting systems: DJ-JJKR-0.6/1KV low-voltage cable. This cable is used in airport power transmission systems, with a long-term operating temperature of ≤70°C. It features ethylene propylene insulation, a short-circuit temperature of ≤250°C for a duration of ≤5S, and an outer sheath made of flame-retardant PVC. The bend radius of the cable is greater than or equal to 15 times the cable's outer diameter.
2. DJ-JJKR-0.6/1KV for special locations, made with special materials.
(1) In case of tensile resistance, steel wire armor should be used. The effect of armor is to reduce the tensile force on the insulation and sheath during cable stretching, thereby protecting the core wire that shields the insulation and sheath.
(2) In areas with a subtropical climate or those with high acidity and alkalinity in the rain, it is advisable to add corrosion-resistant materials to the outer sheath to reduce the corrosion rate of the cable and enhance its service life.
