Flame-retardant Cable Glands

Address Electrical Connection Safety Pain Points & Upgrade Protection Level. In daily operation, cables often face overload, overheating and short-circuit sparks. Standard cable connectors lack effective flame-retardant properties due to material and structural limitations. When exposed to fire, they burn quickly and help spread flames, leading to equipment damage, production downtime, financial losses and safety risks.

Core Performance Highlights: Meet Flame-retardant Standards & Comprehensively Strengthen Product Safety

The core performance of the product meets mainsteam industry flame-retardant standards including V0, with outstanding non-flamemability and self-extinguishing properties. When exposed to open flames, local high temperatures or short circuit sparks, the product is not easy to ignite. Even in contact with a fire source, it can effectively prevent the flame form spreading along the gland to the cable body and surrounding equipment, and can quickly extinguish itself after leaving the fire source.
It effectively blocks fire spread, minimizes accident losses, buys valuable time for emergency response, and provides far better safety than standard cable galnds.

High Temperature Resistance & Long Lifespan
Constructed with special heat-resistant composites, it withstands long-term temperatures up to 150°C and short-term peaks of 200°C. The product remains stable in harsh environments without softening, deformation, cracking or melting.
This prevents leakage, overheating and fire risks caused by aging, extends service life, and lowers maintenance costs.

Low Heat & High Insulation
Optimized conductive structure and precision crimping reduce contact resistance and internal heat buildup, avoiding overheating and combustion risks.
With a high-strength insulation layer to prevent leakage and sparks, it forms triple protection: low heat generation, high flame retardancy and strong insulation.

Wide Environment Adaptability
The cable gland features good waterproof, dustproof, oil-resistant and corrosion-resistant properties, suitable for humid, dusty and harsh industrial conditions.
It performs reliably in outdoor wiring, underground applications, industrial equipment and building installations, maintaining stable flame-retardant performance across various demanding fields.

Application Scenarios

From clean energy infrastructure to heavy industry, modern construction and conventional power networks, flame‑retardant cable glands deliver consistent protection across every critical environment. By combining reliable fire resistance with robust mechanical performance, they serve as a universal safety solution — safeguarding equipment, minimizing operational risk and ensuring uninterrupted power in the applications that matter most.

New Energy
Ideal for NEV battery packs, charging piles, photovoltaics and energy storage systems. Its flame‑retardant performance prevents electrical fires during overload and high‑temperature operation.
Industrial Manufacturing
Suitable for machinery, production lines, chemical and mining equipment. The flame-retardant cable glands withstands harsh industrial conditions and avoids fires that cause downtime and equipment damage.
Construction & Infrastructure
Used in high‑rise buildings, commercial spaces, subways and tunnels. It supports fire safety requirements and prevents flame spread in public facilities.
Conventional Power
Applied in substations, power lines and municipal power systems. It enhances connection safety and ensures stable, reliable power supply.

Technical Support

High-performance Flame-retardant Material
Built with modified flame-retardant polymer composites and high-efficiency flame inhibitors, the gland offers excellent thermal stability and full-volume flame resistance, not just surface treatment.
It resists rapid burning and melting drips under high heat, reliably meeting industry flame-retardant requirements.

Multi-layer Composite Structure
Designed with flame-retardant, thermal-insulation and insulating conductive layers, it isolates flames, blocks heat transfer, and prevents short circuits and sparks.
This multi-layer system forms a full defensive barrier for enhanced fire safety.

Frequently Asked Questions

What makes this cable glands flame-retardant?

We add flame retardants to the raw materials to change the properties of the materials, thereby giving the produced products flame-retardant characteristics.

Do the flame-retardant cable glands need MOQ(Minimum Order Quantity)?

Some sizes need not MOQ because they are in stock, some need, it depends the model, different model different MOQ.

How many levels of flame retardancy are there, and how are they classified?

The UL94 standard defines three main flammability ratings for plastic parts:
V‑0: No burning with flames after removal of the ignition source; no dripping particles that ignite cotton. Highest level of flame resistance.V‑1: Self-extinguishes within a limited time, but allows a small amount of afterflame; no ignitable drips.V‑2: Self-extinguishes within time limits, but may produce dripping particles that can ignite cotton. We just provide V0, the higest flame retardant level.

How can i select the right codel for my project?

You can contact our team with your cable size(the diameter of the cables), environment and safety requirement. We will offer professional selection and matching support.

What benefits does this flame-retardant glands provide?

It reduces the risk of electrical fires, blocks flame spread, lowers potential accidentlosses, and improves the overall safety and reliablity of the entire power connection system.
