三、型号名称 Type and Description

注:

1、该产品可按用户的使用要求，设计成具有阻燃性能或耐火性能的产品。订货时只需在原型号前加“ZR-”表示阻燃型，加“NH-”表示耐火型；

2、电缆的金属屏蔽可按用户要求有两种形式:金属丝编织或金属带绕包；

3、如需软芯导体的电缆，应在原型号后加字母“R”。

Note: 

1: We also produce cable with fame resistant performance or fire resistant performance accordina to the reauirement of customerPrefix “ZR-”should be added to the original type for flame retardant cable and “NH-" added for fire-resistant cable.

2: There are two kinds of metallic shielding. One is metallic wire braiding shielding. The other is metallic tape wrapped shielding.

3: Prefix“R”should be added to the original type for ordering cable with soft conductor;
