Vandal Resistant Telephones: Liquid-Resistant Design and Rust-Proofing

In modern public facilities and industrial environments, telephones are not only a means of communication but also crucial equipment for ensuring safety and emergency communications. However, ordinary telephones are susceptible to damage in harsh environments, particularly from liquid intrusion and vandalism, which directly impacts their service life and reliability. To address this, vandal-resistant telephones have emerged, with their liquid-resistant design and rust-proofing technology as their core advantages.

1. Liquid-Resistant Design

The liquid-resistant design of vandal-resistant telephones is primarily reflected in their body structure and connector design. First, the phone's casing is constructed of high-strength, waterproof materials, typically aluminum alloy or stainless steel, and is sealed to prevent rain, dust, and even water from penetrating. The connectors are waterproof, meeting IP65 or IP66 standards, ensuring the phone remains functional outdoors, in humid, and even rainy environments.

In addition, the buttons and receiver utilize special sealing technology to prevent moisture and other liquids from entering the internal circuitry. For example, the keypad is covered with a highly wear-resistant silicone film, which is not only waterproof but also prevents dust and debris accumulation. The interior of the handset is infused with moisture-resistant material, ensuring clear calls and preventing short circuits and circuit corrosion even in prolonged use in high-humidity environments.

II. Vandal and Shock-Resistant Design

In addition to liquid intrusion, the Vandal Resistant Telephone also prioritizes vandal resistance. The phone's casing is thickened and secured with rust-resistant stainless steel screws, making it less susceptible to damage from vandalism and external impact. The handset cord and buttons are also reinforced to withstand strain and impact, making them suitable for use in high-risk environments such as subway stations, factory floors, and prisons.

III. Rust-Resistant Treatment and Material Selection

Rust-resistant treatment is key to extending the lifespan of Vandal Resistant Telephones. The phone body is often made of stainless steel or metal materials that have undergone galvanizing or spray-coating to effectively resist oxidation and corrosion. Especially in coastal locations or high-humidity environments, where salt spray corrosion is unbearable for ordinary phones, vandal-resistant phones with rust-resistant treatment can significantly extend their lifespan and reduce maintenance costs.

In addition, the internal circuit boards are coated with a moisture-proof coating or epoxy encapsulation to further protect the electronic components from moisture and chemical corrosion. Even in humid environments or prolonged exposure to rain, the phone maintains stable operation without short circuits, poor contact, or signal degradation.

IV. Application Scenarios and Advantages

The Vandal Resistant Telephone is suitable for a variety of harsh environments and public places, including subways, stations, factories, ports, seaside docks, and prisons. Its liquid-resistant and rust-proof treatment not only ensures long-term stable operation, but also reduces equipment maintenance costs and improves the reliability of secure communications. This phone is undoubtedly the best choice for environments requiring 24/7, unmanned communication.
