What is STA Cable?

STA cable’s full name is called steel tape armored cable. It is a kind of armored cable. STA cable used for transmission lines below 35KV. Steel tape armored cable has two layers of steel tape winding in the inner sheath. The steel tape cable is buried underground, so the steel tape plays the role of protecting the cable.

STA Cable characteristics

Long-term allowable working temperature: the long-term working temperature of the conductor should not exceed 90℃, and the z-high working temperature in case of a short circuit should not exceed 250℃ (z-long duration should not exceed 5s).
The cable laying temperature should not be lower than 0℃.
Minimum bending radius (D is the outer diameter of the cable)
Single-core cable: 15D.
Multi-core cable: 12D.
Special characteristics
Flame-retardant products: flame-retardant characteristics meet the requirements of GB/T 19666-2005 “General Rules for Flame-retardant and Fire-resistant Wire and Cable“.
Flame-retardant and fire-resistant products: Flame-retardant and fire-resistant characteristics meet the requirements of GB/T 19666-2005 “General Rules for Flame-retardant and Fire-resistant Wires and Cables”.

Usage of sTA Cable

Armored cable mechanical protection layer can be added to any structure of the cable to increase the mechanical strength of the cable and improve the erosion resistance, and it is a wire and cable designed for the areas that are vulnerable to mechanical damage and highly susceptible to erosion. It can be laid in any way and is more suitable for direct burial in rocky areas.

Armored cable is generally a fixed laying power cable, which is fixed in one place and basically does not move, and the power line transmits electric power.

The purpose of cable plus armored layer can enhance the tensile strength, compressive strength, and other mechanical protection to extend the service life in addition to the above.

The armor has a certain resistance to external force but also can prevent rats from tearing, not to cause power transmission problems through the armor, the bending radius of the armor should be large, the armor layer can be grounded to protect the cable.
