Cable Encapsulado en Tubo (TEC) Descripción
El Cable Encapsulado en Tubo (TEC) es un diseño especializado en el que los conductores o la fibra óptica se encierran en un tubo protector, generalmente de metal (acero inoxidable, cobre) o polímero, lo que proporciona resistencia mecánica, protección ambiental y blindaje EMI. Los productos TEC están disponibles en una variedad de diámetros de tubo, desde 1/8 de pulgada a 5/8 de pulgada, y en diferentes espesores de pared.
Cable Encapsulado en Tubo (TEC) Aplicaciones
- Petróleo y gas: Umbilicales submarinos, registro de fondo de pozo.
- Renovables: Cables entre redes de parques eólicos marinos.
- Industrial: Cadenas de arrastre robóticas, minería, maquinaria pesada.
- Militar/Aeroespacial: Sistemas críticos para EMI.
Cable Encapsulado en Tubo (TEC) Tipos
- TEC de potencia: Conductores de alta tensión para uso industrial/marítimo.
- TEC de fibra óptica: Tubos blindados para detección de telecomunicaciones/OTDR.
- TEC híbrido: Combina potencia y fibra en un solo tubo.
- TEC de fondo de pozo: Resistente a altas temperaturas y presiones para pozos de petróleo y gas
