1kV low-voltage gray-brown-orange heat shrink tubing is made of high-quality cross-linked polyolefin material, specially designed for 1kV low-voltage circuits. Its insulation strength meets low-voltage protection standards, effectively preventing electric leakage and cable abrasion, and avoiding electric shock hazards.

The core gray, brown and orange three-color design precisely meets the requirements for polarity, circuit and warning identification in low‑voltage wiring, complying with electrical wiring marking specifications:

gray for neutral wire, brown for live wire, and orange for warning/backup circuit.

It enables quick identification of line properties and greatly reduces the risk of wrong connection during construction and maintenance.

It features a 2:1 shrink ratio upon heating, fitting tightly on the cable surface without bubbles or gaps. It is friction‑resistant, UV‑resistant and resistant to mild acid and alkali corrosion, operating stably in a wide temperature range from -40℃ to 125℃. It also has flame‑retardant properties with long‑lasting color, ensuring standardized operation of low‑voltage circuits.

All‑scene low‑voltage application, worry‑free three‑color identification!

Used in household circuit renovation to clearly distinguish gray neutral wires and brown live wires, avoiding potential electrical safety risks.

Used in low‑voltage distribution boxes to divide different circuits and warning lines with three colors, improving operation and maintenance efficiency through standardized identification.

Used in building weak‑current engineering and industrial low‑voltage circuits to meet the needs of dense wiring with accurate and convenient three‑color distinction.

Used in low‑voltage side connections of new energy systems to provide insulation protection while clarifying line properties, complying with construction standards.

It is the preferred accessory for three‑color identification and protection of 1kV low‑voltage circuits.
