HZD2820-G
HZD2820-G is a high flame-retardant 150°C irradiation cross-linked LSZH compound — VW-1 capable for rail transit, marine and high-temperature safety cable.
Orange cable compound pellet sample
01 / 02Material — High flame-retardant irradiation cross-linked LSZH compound
Overview
HZD2820-G is a 150°C halogen-free cable compound with a reinforced flame-retardant package (oxygen index 42 typical), colorable, built on a polyolefin base with inorganic flame retardants, antioxidants and lubricants. It serves electronic equipment wire and metro cable insulation where both sustained heat and fire safety matter.
Used as both insulation and jacket in a properly designed construction, cable made from HZD2820-G passes the UL VW-1 vertical flame test, with thermal aging verified at 180°C × 168 h.
Packaging & Storage
Supplied in aluminum-plastic bags with kraft paper lining, 25 kg net per bag. Store in a dry, well-ventilated warehouse.

Grade qualification
Validate the grade against the cable, process and target standard
Published properties establish the review baseline. Cable construction, processing conditions and a line trial complete the grade decision.
- 01
Define the duty profile
Confirm cable construction, operating temperature, flame class and environmental requirements.
- 02
Review the published data
Match requirements, typical values and test methods to the finished-cable target.
- 03
Run a controlled line trial
Set drying, temperature, screw and irradiation conditions from the grade processing card.
- 04
Approve the production window
Record surface, dimensions, mechanical results and finished-cable tests before volume production.
