Mouse and ant prevention type low-smoke halogen-free armored control cable with nylon protective sleeve

Abstract

A mouse and ant prevention type low-smoke halogen-free armored control cable with a nylon protective sleeve comprises a plurality of copper conductors (1). A low-smoke halogen-free insulating layer (2) wraps the outer edge of each copper conductor (1) to form an insulating cable core. The insulating cable cores are wrapped by a low-smoke halogen-free inner protective layer (3) after being cabled, wherein one insulating cable core serves as the center, the rest of the insulating cable cores surround the center insulating cable core to form a ring, and a zinc-plated steel belt overlapped armor (4) is added to the outer circle of the ring and then wrapped by the nylon protective sleeve (6). The mouse and ant prevention type low-smoke halogen-free armored control cable is characterized in that a mouse and ant prevention type low-smoke halogen-free protective sleeve (5) is arranged between the zinc-plated steel belt overlapped armor (4) and the nylon protective sleeve (6) in a wrapping mode. The mouse and ant prevention type low-smoke halogen-free armored control cable has the advantages of being capable of preventing mice and ants, free of toxtin, environmentally friendly, and resistant to moisture, oil and corrosion.

Description

technical field [0001] The invention relates to a control cable with high usage requirements, in particular to an armored control cable with a nylon sheath rodent-proof type low-smoke and halogen-free sheath. Background technique [0002] At present, the control cables used in most control circuits are made of ordinary polyvinyl chloride plastic insulated and sheathed cables, that is, copper conductors are covered with PVC insulation, and the cores are cabled and covered with PVC inner sheaths. With armor, and then covered with PVC outer sheath. The production process of the cable is simple and the performance is qualified, so it is widely used. However, this type of control cable has a general environmental adaptability, is often damaged by rats, ants, etc., has poor moisture resistance and corrosion resistance, and has a short lifespan. If it burns, it will emit dense black smoke and produce black solid derivatives. It releases irritating and toxic halogen acid gas, whic...
