The Tubular Cell offers outstanding reliability over an expected working life of 10 to 12 years in float charge applications. These cells are capable of high cycling. The round tube has the following advantages over the conventional square tube:

Specification Data

	It offers a more uniform active material distribution around the supporting spines, resulting in more efficient utilisation .
	It is less prone to distortion under operating conditions .
	It offers a greater surface area for a specific plate dimension, affording higher energy density It has a small footprint.
Applications: Emergency Lighting Telecommunications Railway Signalling DC Emergency Systems			Cells comply with SABS IEC 60896-1:1987 and conform to SABS ISO 9001 Quality Management System.

Design features:

POSITIVE PLATE: The tubular gauntlet plate construction consists of special lead alloy spines in complete contact with superior active material, effectively retained by woven terylene tubes. The terylene gauntlets, which are resin impregnated, combine high tensile strength with resilience, retaining the active material while enabling the electrolyte to penetrate freely. This ensures a high power output per unit volume.

NEGATIVE PLATE: The negative plate is of a special alloy grid containing a highly-porous paste formulation, giving a balanced performance and life, and complementing the positive plate construction.

CONTAINERS: Moulded, DIN standard, transparent styrene acrylonitrile, giving very high insulating properties which eliminate the use of insulators. Age or acid contact will not cause deterioration.

LID: Moulded from opaque styrene acrylonitrile

SEPARATORS: High quality, microporous rubber separators. Chemically inert with a high degree of porosity, they offer minimum internal resistance. These wraparound separators prevent short-circuiting caused by mossing

VENT PLUGS: The special design effectively returns all acid spray to the cell, yet permits free exit of oxygen and hydrogen.
END BUFFERS: PVC end buffers provide additional lateral support at each end of the element, ensuring a compact assembly to prevent the plates from splaying.
