Lander provides a full range of capillary tubes engineered for downhole control, hydraulic injection,
chemical delivery, monitoring, and harsh-environment operations.
Our material options ensure reliability under extreme pressure, high temperature, and corrosive media —
delivering long-term performance in the world’s toughest wells.
High Temperature Cables are designed for long-term operation in extreme thermal, chemical, and mechanical environments.
Insulation is extruded under tightly controlled temperature and pressure conditions.
This process ensures uniform wall thickness, strong adhesion, and excellent thermal performance.
The cable is cooled gradually to prevent internal stress and maintain insulation integrity.
Before shipment, all cables undergo final inspection to verify performance, dimensions, and packaging compliance.
Cables are carefully spooled and packaged to prevent deformation and damage during transportation.
Copper and aluminum conductors are carefully stored and managed in a controlled warehouse environment. Each batch undergoes verification for conductivity, dimensional consistency, and surface condition before entering the production line, ensuring stable electrical performance and reliable processing throughout cable manufacturing.
Annealed single wires are stranded into conductors to achieve the required current capacity, flexibility, and mechanical strength.
Insulation materials are extruded over the stranded conductor under controlled conditions to provide electrical insulation and thermal protection.
An inner sheath is applied to protect the cable core and provide a stable base for armoring.
Metal armor is applied to enhance mechanical strength and resistance to external impact and downhole stresses.
Cables are carefully spooled and packaged to prevent deformation and damage during transportation.
